反应详情

Sodium cyanide (0.245 g, 5 mmol) was added to a mixture of anthranilic acid (0.411 g, 3 mmol) and acetone (1 ml, 13.6 mmol) in acetic acid 90% (3 ml). The reaction mixture was stirred at room temperature for 12 h and then 50 ml of ethyl acetate was added. The organic layer was washed with brine (3×30 ml). The organic layer was dried over magnesium sulfate, concentrated and chromatographed (dichloromethane:acetone, 90:10) to yield 22a (0.551 g, 2.7 mmol, 90%) as a brown solid.
