Procedure

A solution of 3.38 g (0.015 mol) of sodium m-nitrobenzenesulfonate in 15 ml of water was added to a solution of 7.0 g (0.015 mol) of N,N-bis(2-cyclohexanonyloxyethyl)-N-methylbenzylammonium chloride (prepared as described in Example 23) in 50 ml of water. An oily precipitate immediately formed. The oil was rinsed twice with water, dissolved in methylene chloride, dried over MgSO4 and concentrated. The resultant oil was crystallized with P-513 ligroine and warmed. The crystals were collected, washed with ether, dried and recrystallized from 2-butanone. The yield of product was 2.64 g; mp=123°-4.5° C.
