Hydrochloric Acid → 4-(quinolin-2-ylmethoxy)benzoic Acid

関与物質

反応手順

To a solution of 4-(Quinolin-2-ylmethoxy)-benzoic acid methyl ester (500 mg, 1.7 mmole) in tetrahydrofuran (8.5 ml) and methanol (3 ml) was added 1N NaOH (3.4 ml, 2 eq.). The reaction mixture was stirred at ambient temperature for 16 h. To the reaction mixture was added 50 ml of brine and the pH was adjusted to 3 with 1N HCl to provide a white precipitate which was filtered and dried to provide the title compound as a white solid (463 mg, 98%). 1H NMR (400 MHz, DMSO) δ 8.39 (d, J=8.3 Hz, 1 H), 7.99 (m, 2 H), 7.81 (M, 2H), 7.76 (dt, J=8.3, 1.7 Hz, 1 H), 7.64 (d, J=8.3 Hz, 1 H), 7.60 (dt, J=7.9, 1.3 Hz, 1 H), 7.12 (M, 2 H), 5.41 (s, 2 H); MS: (M+H m/z=280.2).
