実験手順
Using a procedure similar to Example 204, step (a), 56 mg (0.21 mmol) of methyl 4-[(aminothioxomethyl)amino]-5-methylthiothiophene-2-carboxylate was allowed to react with 40 mg (0.21 mmol) of bromotrifluoroacetone (Aldrich Chemical Co., Milwaukee, Wis.) to afford 40.3 mg (54%) of methyl 4-{[4-hydroxy-4-(trifluoromethyl)(1,3-thiazolin-2-yl)]amino}-5-methylthiothiophene-2-carboxylate. Mass spectrum (ESI, m/z): Calcd. for C11H11F3N2O3S3, 373.00 (M+H), found 373.0.
