실험 절차

Using a procedure similar to Example 204, step (a), 51 mg (0.19 mmol) of methyl 4-[(aminothioxomethyl)amino]-5-methylthiothiophene-2-carboxylate was allowed to react with 41.4 mg (0.38 mmol) of 2-bromopropiophenone (Aldrich Chemical Co., Milwaukee, Wis.) in 2 mL of DMF for 4 h. Concentration in vacuo of the reaction mixture afforded 73 mg (100%) of methyl-4-[(5-methyl-4-phenyl(1,3-thiazol-2-yl))amino]-5-methylthiothiophene-2-carboxylate. Mass spectrum (ESI, m/z): Calcd. for C17H16N2O2S3, 377.05 (M+H), found 377.2.
