실험 절차

A solution of 2-[(cyclopropyl-methyl-amino)-methyl]-4-(3-fluoro-4-methoxycarbonylmethyl-phenylethynyl)-benzoic acid isopropyl ester (Intermediate 124, 0.04 g, 0.09 mmol) in a mixture of methanol (2 mL), tetrahydrofuran (2 mL) and water (1 mL) was treated with lithium hydroxide monohydrate (0.042 g, 1 mmol) and the resulting reaction mixture was stirred at ambient temperature for 2 h. The volatiles were evaporated in vacuo, the residue was neutralized with saturated, aqueous ammonium chloride solution and extracted with ethyl acetate. The combined organic extract was dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to a solid. Preparative reverse phase HPLC using 10% water in acetonitrile as the mobile phase afforded the title product as a white solid (0.026 g, 54%). 1H NMR (300 MHz, CDCl3): δ 7.71 (d, 1H, J=8.1 Hz), 7.64 (s, 1H), 7.41 (d, 1H, J=8.1 Hz), 7.17-7.09 (m, 3H), 5.20 (heptet, 1H, J=6.3 Hz), 4.16 (s, 2H), 3.54 (s, 2H), 2.34 (s, 3H), 1.91 (m, 1H), 1.36 (d, 6H, J=6.3 Hz), 0.50-0.41 (m, 4H).
