39.71% | With manganese(IV) oxide; In dichloromethane; at 25℃; for 16h; | To a solution of (5-methylisoxazol-3-yl) methanol (10.0 g, 88.0 mmol, 1 eq.) in DCM (100 mL) was added MnO2 (38.4 g, 442 mmol, 5 eq.). The mixture was stirred at 25 C for 16 hours and filtrated. The filtrate was concentrated in vacuum to give 5- methylisoxazole-3-carbaldehyde (6.50 g, 35.0 mmol, 39.71 % yield) as yellow oil.1H NMR (400 MHz, CDCl3) δ = 10.12 (s, 1H), 6.40 (s, 1H) 2.53 (s, 3H). |
