Sodium 3-nitrobenzenesulfonate → N-(2-(Benzoyloxy)ethyl)-N,N-dimethyl-n-octadecylammonium m-nitrobenzenesulfonate

Participants

Reaction Steps

To a solution of 26.33 g (0.05 mol) of N-(2-(benzoyloxy)ethyl)-N,N-dimethyl-n-octadecylammonium bromide (prepared as described in Example 36) dissolved in 500 ml of water at 70° C. was added a solution of 11.26 g (0.05 mol) of sodium m-nitrobenzenesulfonate in 100 ml of water. The resultant mixture was extracted with methylene chloride. The water layer was separated and the organic layer was dried over MgSO4 and concentrated. The solid was recrystallized from ethyl acetate, collected, washed with ligroine, and dried to yield 21.7 g of the title compound; mp=80°-3° C. ##STR26##
