Procedure
A solution of 75 mg (0.3 mmol) of methyl 4-(aminothioxomethyl)-5-methylthiothiophene-2-carboxylate (Maybridge, Cornwall, UK) was reacted with 105 mg 1-[3,5-Bis(trifluoromethyl)phenyl]-2-bromopropan-1-one in a manner similar to Example 8, step (a) to give, after preparative thin-layer chromatrography purification, methyl 4-{4-[3,5-bis(trifluoromethyl)phenyl]-5-methyl(1,3-thiazol-2-yl)}-5-methylthiothiophene-2-carboxylate (16.2 mg, 11%) as a solid. 1H-NMR (DMSO-d6; 300 MHz) δ8.41 (m, 2H), 8.18 (m, 2H), 3.86 (s, 3H), 2.75 (s, 3H), 2.71 (s, 3H). Mass spectrum (MALDI-TOF, CHCA matrix, m/z): Calcd. for C19H13NO2S3F6, 498.0 (M+H), found 497.6.
