Reaction Steps
20 mg of platinum oxide are added to a solution of 4.28 g of 2-chloro-3-methyl-4-hydroxy-5-(3-m-nitro-phenoxyphenyl)-6,7-dihydrothieno[2,3-b]pyridin-6-one in 50 ml of 95% ethanol. Hydrogen is passed through the solution until three molar equivalents have been absorbed. The platinum is filtered off and the alcohol is distilled off. 2-Chloro-3-methyl-4-hydroxy-5-(3-m-aminophenoxyphenyl)-6,7-dihydrothieno[2,3-b]pyridin-6-one is obtained.
