반응 단계
A solution of 23.0 g. (0.09 mol) of 2,4-diethoxycarbonyl-3-methyl-5-aminothiophene in 250 ml. of acetic anhydride was heated to 100° C. for 1.5 hrs. The resulting mixture was cooled in an ice bath and the precipitated crystals were filtered to yield 2,4-diethoxycarbonyl-3-methyl-5-acetylamino-thiophene, m.p. 130°-131° C.
