37% | Stage #1: With O-Methylhydroxylamin In tetrahydrofuran at 20℃; for 3 h; Stage #2: With hydrazine hydrate In tetrahydrofuran at 80℃; for 3 h; |
NH2OMe (174 mg, 2.08 mmol, 2.0 eq.) was added to a stirred solution of 2-fluoro-4-trifluoromethyl benzaldehyde 13 (200 mg, 1.04 mmol, 1.0 eq.) in THF (5 mL) at rt. After stirring at rt for 3 h, (NH2)2·H2O (67 mg, 2.08 mmol, 2.0 eq.) was added to the reaction mixture and reflux for 3 h. Then the reaction mixture was quenched with sat Na2S2O3(aq) and extracted with EtOAc, dried over MgSO4, and evaporated in reduced pressure, to give the crude product. Purification with Yamazen automated chromatography with Hex:EtOAc = 9:1 as eluent to give 14 (121 mg, 37percent) as a colourless solid, 1H NMR (300 MHz, CDCl3) δ 10.57 (1H, br s), 8.18 (1H, s), 7.89 (1H, dd, J = 9.0, 0.5 Hz), 7.42 (1H, dd, J = 9.0, 3.0 Hz), 7.42 (1H, dd, J = 9.0, 3.0 Hz); MS (ESI) m/z 203 [(M + Na)+], RT 1.00 min (Condition A). |
