Reaction Steps
A mixture of (2'-acetylamino-4',6'-dimethoxyphenyl)ethanone (compound 75-3, prepared in Preparation 75) (0.237 g, 1.0 mmol), potassium hydroxide (0.2 g, 3.57 mmol), water (0.2 ml), and ethanol (2 ml) is heated to reflux for one hour. The solvent is distilled under reduced pressure, and the residue is extracted with dichloromethane. The extract is washed with water, dried, and the solvent is removed to yield a crystalline residue. Recrystallization from ethyl acetate gives (2'-amino-4',6'-dimethoxyphenyl)ethanone as a crystalline solid (0.114 g, 58%, m.p.=104°-105° C.).
