実験手順

A solution of 2-(4-{8-[(cyclopropyl-methyl-amino)-methyl]-2,2,4,4-tetramethyl-chroman-6-ylethynyl}-phenyl)-2-methyl-propionic acid methyl ester (Intermediate 15, 0.040 g, 0.084 mmol) in methanol (2.5 mL) and tetrahydrofuran (2.5 mL) was treated with a 2M solution of sodium hydroxide (1 mL, 2 mmol) and the resulting reaction mixture was refluxed overnight. The volatiles were evaporated in vacuo to a residue that was 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 an oil. Preparative reverse phase HPLC on a partisil 10 ODS-3 column using 10% water in acetonitrile as the mobile phase afforded the title compound (0.008 g, 27%).
