With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.139-07-1,N-Benzyl-N,N-dimethyldodecan-1-aminium chloride,as a common compound, the synthetic route is as follows.

EXAMPLE 3 Preparation of 2-methoxybenzenesulfochloride A diazonium salt solution, prepared similarly to Example 1 from o-anisidine, was brought into intimate contact, at 0 C., with a solution of 100 ml of 1,2-dichloroethane and 21 g (0.33 mole) of SO2, and was then decomposed using 0.5 g of CuCl2 and 1 g of dodecyldimethylbenzylammonium chloride at 40 C. 4.3 g of a 30% strength by weight aqueous hydrogen peroxide solution (=38 millimoles of H2 O2) were then added to the mixture, and after a reaction time of 3 minutes the batch was worked up in a conventional manner. The yield of 2-methoxybenzenesulfochloride was 80%; boiling point 134-138 C./0.7 mbar.

Solution A: A 5 mL volume of 160 mM sodium molybdate dihydrate is diluted with 5 mL of water and the acidity of the solution is adjusted to pH 2 with 0.1 M sulfuric acid. About 1 mL of 36% hydrogen peroxide is added and the resulting solution is diluted to 20 mL with water. Solution B: Oxalic acid dihydrate (0.106 grams) is added into 2.5 ml of an aqueous solution of alkyldimethylbenzylammonium chloride (0.604 grams) and the resulting solution is diluted to 5 mL with water. In an ice-cold condition with vigorous stirring, solution A is added dropwise into solution B and the pH of the resulting solution is maintained at pH 2 by adding sulfuric acid. After 5 minutes, the formation of the precipitate is observed. The reaction mixture is centrifuged and the precipitate is washed 2-3 times with water and dried under vacuum (yield of compound 3 was 85%).

The API-IL benzalkonium salicylate was prepared from benzyldimethyldodecylammoniumchloride (benzalkonium chloride) and sodium salicylate according to a procedure similar tothat described in the literature [8]. Sodium salicylate (0.93 g, 5.8 mmol) and benzyldimethyldodecylammoniumchloride (2.05 g, 5.8 mmol) were dissolved in 20 mL of acetone/H2O(1:1). The reaction mixture was stirred overnight at room temperature. The remaining suspensionwas diluted with 20 mL of distilled water. The product was extracted with dichloromethane.Sodium chloride as a byproduct was removed by washing the dichloromethane phase successivelywith water. The presence of chloride ions in the washings was detected using AgNO3solution. The dichloromethane was evaporated under reduced pressure. The obtained API-ILwas further dried at 343 K in vacuum for 8 h. The water content of the API-IL was determinedby a Karl-Fischer measurement, and the value was about 350 ppm. The synthesized API-ILwas characterized by 1H NMR (Bruker DPX) and IR (Nicolet IR-470).The characterization values obtained are: IR (KBr, cm-1): 3437(s), 3027(w), 2921(s),2852(s), 1638(s), 1590(s), 1484(s), 1456(s), 1219(s), 1137(m), 758(m), 735(m);1H NMR:(400 MHz, CDCl3)delta in ppm: delta 7.97 (dd, J = 7.7, 1.7 Hz, 1H), 7.48 (m, 6H), 6.87 (d,J = 8.2 Hz, 1H), 6.76 (t, J = 7.4 Hz, 1H), 4.82 (s, 2H), 3.36 (m, 2H), 3.21 (s, 6H), 1.74 (s, 2H),1.24 (d, J = 7.4 Hz, 18H), 0.88 (t, J = 6.8 Hz, 3H). The 1H NMR spectra of BaSal is presentedin Fig. S1 of the Supplementary Material.Thermal stability was measured on a STA 409 PC simultaneous thermal analyzer (Germany)in the range of 303-773 K at a heating rate of 10 K¡¤min-1 under an air environment. Itcan be seen from Supplementary Fig. S2 that BaSal has good thermal stability with the lowdecomposition temperature of 454 K., 139-07-1
