실험 절차

A solution of (E)-3-{4-[5-(cyclopropyl-methyl-amino)-4-methoxy-8,8-dimethyl-5,6,7,8-tetrahydro-naphthalen-2-ylethynyl]-cyclohexa-2,4-dienyl}-2-methyl-acrylic acid methyl ester (Intermediate 87, 0.12 g, 0.25 mmol) in methanol (3 mL) and tetrahydrofuran (2 mL) was treated with a 3M solution of potassium hydroxide (1 mL, 3 mmol) and the resulting reaction mixture was stirred at ambient temperature overnight. The reaction mixture was neutralized with 5% aqueous hydrochloric acid and extracted with ethyl acetate. The organic phase was washed with water and brine, and dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to a residue that was recrystallized from hot acetonitrile to afford the title product as a white solid (0.055 g, 49%).
