実験手順

A solution of 75 mg (0.3 mmol) of methyl 4-(aminothioxomethyl)-5-methylthiothiophene-2-carboxylate (Maybridge, Cornwall, UK) was reacted with 90 mg (0.3 mmol) of 2-bromo-1-[3-fluoro-5-(trifluoromethyl)phenyl]propan-1-one in a manner similar to Example 8, step (a) to give, methyl 4-{4-[3-fluoro-5-(trifluoromethyl)phenyl]-5-methyl(1,3-thiazol-2-yl)}-methylthiothiophene-2-carboxylate (31.9 mg, 24%) as a solid. 1H-NMR (DMSO-d6; 300 MHz) δ8.17 (s, 1H), 7.98 (m, 1H), 7.95 and 7.92 (m, 1H, 1:1 ratio conformers), 7.77 and 7.74 (m, 1H, 1:1 ratio conformers), 3.87 (s, 3H), 2.75 (s, 3H), 2.70 (s, 3H). Mass spectrum (MALDI-TOF, CHCA matrix, m/z): Calcd. for C18H13NO2S3F4, 448.0 (M+H), found 448.0.
