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.
139-07-1, As the paragraph descriping shows that 139-07-1 is playing an increasingly important role.
