실험 절차
To a stirred mixture of benzthiophene-2-one (1.50 g, 0.01 m), phenylcarbamate (1.4 g, 0.01 m), and hexamethylphosphorictriamide (2.2 ml) at 5° C. is added sodium hydride (0.24 g, from 0.4 g 60% mineral oil dispersion), and the resultant mixture stirred at ambient temperatures for 5 hours. The volatiles are removed under high vacuum, and the residue triturated well with hexane and then with water to yield 2-hydroxybenzo(b)thiophene-3-carboxamide.
