실험 절차
A mixture of N-benzyl-2-hydroxybenzo(b)thiophene-3-carboxamide (4.3 g, 0.016 m), 10% palladium on carbon (2.0 g), and ethanol are stirred under a hydrogen atmosphere (40 p.s.i.) at 35° C. until hydrogen uptake is completed. The reaction mixture is filtered, the cake washed well with warm ethanol, and the combined filtrates concentrated in vacuo to yield 2-hydroxybenzo(b)thiophene-3-carboxamide.
