Reaction Steps

Aqueous 6N sodium hydroxide solution (3 ml) was added to a solution of 5-acetylamino-2,4,6,7-tetramethyl-2-(2-phenylethyl)-2,3-dihydrobenzofuran (0.7 g, 2.1 mmol) in methanol (3 ml) and the mixture was heated at 200° C. in an autoclave for 18 hours. The reaction mixture was diluted with water and the product was extracted with ethyl acetate. The extract was washed with water, dried and concentrated. The residue was purified by column chromatography on silica gel (isopropyl ether-ethyl acetate, 2:1). The crude crystals were recrystallized from hexane to obtain the desired compound (0.32 g, yield: 54.5%), m.p. 45°-46° C. (dec).
