0.38 g of 55% sodium hydride and 10 ml of dimethylformamide were weighed out and a solution of 2 g of 2-(4-hydroxyphenyl)-5-n-decylpyrimidine in 3 ml of dimethylformamide was added dropwise thereto under ice cooling. After the completion of the addition, the resulting mixture was stirred at room temperature for one hour. Then p-toluene-sulfonate of optically active 4-methyloctanol was added dropwise thereto and the resulting mixture was stirred at 90° C. for two hours. After cooling, the reaction mixture was poured into ice/water, extractd with diethyl ether and dried followed by removal of the solvent. The residue was purified on a silica gel column to thereby give 1.5 g of optically active 2-(4-(4-methyloctoxy)phenyl)-5-n-decylpyrimidine.
