Participants

Reaction Steps

0.8 g of N,N'-dicyclohexylcarbodiimide is added within 5 minutes while stirring to a solution of 1.0 g of 4-(2-[4-pentylphenyl]-5-pyrimidinyl)phenol, 0.4 g of caproic acid and 0.05 g of 4-(dimethylamino)pyridine in 30 ml of dichloro-methane. The reaction mixture is stirred overnight, then filtered, the filtrate is washed with saturated sodium bicarbonate solution and with water and concentrated. Chromatography of the residue on silica gel with hexane/ethyl acetate (vol. 4:1) and two-fold recrystallization of the fractions which are pure according to thin-layer chromatography give 1.0 g of 4-(2-[4-pentylphenyl]-5-pyrimidinyl)phenyl hexanoate; m.p. (C-SC) 124° C., phase transition (SC -SA) 185° C., cl.p. (SA -I) 224° C.
