実験手順

A solution of 2-(o-methoxyphenoxymethyl)thiazolidine (100 g) in 1,2-dichloroethane (250 ml) cooled at 10° is heated, under stirring, with triethylamine (68 ml) and a solution of α-chloroacetylchloride (36.2 ml) in 1,2-dichloroethane (50 ml) is added dropwise. After 1 hour, the mixture is washed with water, dried on Na2SO4 and evaporated to dryness. Subsequent crystallization from propan-2-ol gives 3-α-chloroacetyl-2-(o-methoxyphenoxymethyl)thiazolidine m.p. 87°-88° C. (100 g).
