Reaction Steps
5-(Methoxycarbonyl)-2-(methylthio)-thiophene-3-thiocarboxamide (100 mg, 0.4 mmol, Maybridge Chemical Company, Cornwall, UK) was dissolved in acetone (20 ml). To this solution, methyl 4-(2-bromoacetyl)-5-methylthiothiophene-2-carboxylate (112 mg) as prepared in previous step was added and heated at reflux for 3 h. At this point the solid that precipitated was filtered off and washed with acetone and dried under vacuum to give 82 mg (65%) of methyl 5-methylthio-4-(2-phenyl(1,3-thiazol-4-yl))thiophene-2-carboxylate. 1H-NMR (CDCl3; 300 MHz) δ2.67 (s, 3H), 3.91 (s, 3H), 7.44-7.49 (m, 3H), 7.61 (s, 1H), 8.03-8.06 (m, 2H), 8.28 (s, 1H).
