反応手順
A solution of 3-acetyl-isoquinoline (0.65 g), hydroxylamine (0.29 g) and sodium acetate (0.47 g) in a mixture of methanol (20 ml) and water (3 ml) was heated to reflux for 1.5 hours. The reaction was then poured into water and extracted with ethyl acetate. The combined extracts were dried, concentrated and triturated with hexane to give 3-acetyl-isoquinoline oxime (0.63, 89% yield) as a white crystalline solid m.p. 135°-142° C.; 1H NMR: 2.50(3H,s); 7.61(1H,t); 7.70(1H,t); 7.87(1H,d); 7.99(1H,d); 8.11(1H,s); 9.28(1H,s) ppm.
