Procedure

Methyl 4-{2-[(2-bromo-4-methylphenyl)amino](1,3-thiazol-4-yl)}-5-methylhiothiophene-2-carboxylate hydrobromide: Methyl 4-(2-bromoacetyl)-5-methylthiothiophene-2-carboxylate (60 mg, 0.19 mmol) was allowed to react with 2-bromo-4-methylphenyl thiourea (47 mg) as described in Example 154, step (a) to give 62 mg (61% yield) of methyl 4-{2-[(2-bromo-4-methylphenyl)amino](1,3-thiazol-4-yl)}-5-methylthiothiophene-2-carboxylate hydrobromide. 1H NMR (DMSO-d6, 300 MHz) δ 2.28 (s, 3H), 3.82 (s, 3H), 7.19-7.23 (m, 1H), 7.27 (s, 1H), 7.48 (m, 1H), 8.14, 8.17 (s, 1H rotomer), 9.52, 9.72 (bs, 1H rotomer); Mass Spectrum (ESI) m/z calcd. for C17H15BrN2O2S3, 455.42 (M+H), found 455.0, 457.0.
