実験手順
In substantially the same manner as in Reference Example 47, 4,5,6,7-tetrahydro-2-benzothiophene carboxamide was allowed to react with 1,3-dichloroacetone to give 4-chloromethyl-2-(4,5,6,7-tetrahydro-2-benzothienyl)oxazole. The yield was 53%. Recrystallization from ethyl acetate-hexane gave colorless needles, mp 102-103° C.
