実験手順

A solution of (4-{8-[(cyclopropyl-methyl-amino)-methyl]-2,2,4,4-tetramethyl-chroman-6-ylethynyl}-2-fluoro-phenyl)-acetic acid methyl ester (Intermediate 13, 0.060 g, 0.13 mmol) in methanol (1 mL) and tetrahydrofuran (3 mL) was treated with a 1M solution of sodium hydroxide (0.4 mL, 0.4 mmol) and the resulting reaction mixture was stirred at ambient temperature overnight. The volatiles were evaporated in vacuo to a residue that was washed with hexane, neutralized with saturated aqueous ammonium chloride solution 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 afford the title product as a yellow oil (0.056 g, 95%).
