反応手順

4.9 g (0.018 mol) of 2-hydroxyhexadecanoic acid and 5.4 g (0.018 mol) of 2-aminooctadecane-1,3-diol were mixed in a glass tube; the mixture was irradiated with microwaves with the aid of a Synthewave 402™ apparatus from Prolabo--frequency 2450±50 MHz--modulable power rating 300 W. After an irradiation of 15 minutes at 155° C.±5° C., the reaction mixture was solubilized at high temperature in a mixture of 80 ml of ethyl acetate and 20 ml of heptane. The precipitate obtained was recrystallized from ethanol and 7 g of expected pure product were obtained with a yield of 70%.
