Reaction Steps

Methyl 5-methylthio-4-[2-(3-quinolylamino)(1,3-thiazol-4-yl)]thiophene-2-carboxylate: Methyl 4-(2-bromoacetyl)-5-methylthiothiophene-2-carboxylate (90 mg, 0.28 mmol) was allowed to react with amino(3-quinolylamino)methane-1-thione (59.1 mg) as described in Example 154, step (a) to give 107.5 mg (78% yield) of methyl 5-methylthio-4-[2-(3-quinolylamino)(1,3-thiazol-4-yl)]thiophene-2-carboxylate hydrobromide. 1H NMR (DMSO-d6, 300 MHz) δ 2.75 (s, 3H), 3.84 (s, 3H), 7.52 (s, 1H), 7.92-8.05 (m, 2H), 8.22 (s, 1H), 9.22 (m, 2H); Mass Spectrum (ESI) m/z calcd. for C19H15N3O2S3, 413.54 (M+H), found 414. 1.
