To a mixture of 2-amino-4-methyl-5-phenyl-3-thiophencarboxamide (0.18 g) in glacial acetic acid (5 mL) and water (0.5 mL) was added sodium isocyanate (101 mg). The resulting solution was stirred at room temperature for 4 h and then poured into water. The precipitate was filtered off and washed with more water. The product was chromatographed on silica gel eluting with dichloromethane/methanol mixtures to give the title product as a solid (30 mg).
