실험 절차

0.2 mol of methyl 3-(3,5-dicyclohexyl-4-hydroxyphenyl)propionate, 0.1 mol of 1,5-dihydroxy-3-thiapentane and 2 ml of tetrabutyl titanate are heated for 8 hours at 150° C. as described in Example 2, during which time the methanol forming distills off. After working up, the yield of product is 25.5% of theory.
