실험 절차

In 20 ml of dry dichloromethane were dissolved 3.04 g (10 millimoles) of optically active (+)-4-(1-hexyloxy-2,2,2-trifluoroethyl)benzoic acid, 3.12 g (10 millimoles) of 5-decyl-2-(p-hydroxyphenyl)pyrimidine and 0.2 g of 4-pyrrolidinopyridine. Then, 2.5 g (12 millimoles) of dicyclohexylcarbodiimide was added and the resulting mixture was stirred at room temperature for 6 hours. After the reaction, 5% aqueous solution of acetic acid was added and the whole was extracted with dichloromethane. The organic layer was washed successively with water and 7% aqueous solution of sodium hydrogen carbonate and dried on anhydrous magnesium sulfate, and then the solvent was distilled off and the residue was purified by silica gel column chromatography. Thus, 4.97 g (yield 83% ) of optically active 5-decyl-2-(p-hydroxyphenyl)pyrimidine (+)-4-(1-hexyloxy-2,2,2-trifluoroethyl)benzoate was obtained.
