実験手順

A solution of 2-{4-[5-(cyclopropyl-methyl-amino)-4-methoxy-8,8-dimethyl-5,6,7,8-tetrahydro-naphthalen-2-ylethynyl]-phenyl}-propionic acid methyl ester (Intermediate 84, 0.115 g, 0.26 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 subjected to flash column chromatography over silica gel (230-400 mesh) using 8% methanol in ethyl acetate as the eluent to afford the title product as a yellow solid (0.062 g, 56%).
