실험 절차
Methyl o-mercaptophenylmalonamate (4.5 g, 0.02 m) and dried dimethylformamide (50 ml) at 10° C. is treated with sodium methoxide (3.2 g, 0.06 m) under a nitrogen atmosphere, and the resultant mixture allowed to stir at ambient temperature until no starting malonamate remains (thin-layer analysis). The reaction mixture is added to a stirred excess dilute hydrochloric acid-ice mixture, aged and filtered to yield 2-hydroxybenzo(b)thiophene-3-carboxamide.
