Participants

Reaction Steps

A mixture of 1.0 g of dodecyl(2-hydroxycyclohexyl)-dimethylammonium bromide prepared in Example 3, 5 ml of acetic anhydride and 5 ml of dry pyridine was allowed to stand at room temperature for about 16 hours. Twenty-five milliliters of water was added and the mixture allowed to stand for one hour. The solution was concentrated under reduced pressure at 50° using a rotary film evaporator. Two 20 ml portions of water were added successively to aid removal of pyridine, followed by absolute ethanol for final drying. The residue was 1.11 g of (2-acetoxycyclohexyl)(dimethyl)dodecylammonium bromide. The ir spectrum was consistent with the assigned structure and clearly showed esterification of the hydroxy group to have occurred.
