Reaction Steps

A mixture of 2.4 g of 3-cyano-beta-carboline, 1.1 g of hydroxylamine-hydrochloride, 200 ml of 99% ethanol and 5.2 ml of a potassium carbonate solution (2.2 g of potassium carbonate in 10 ml of water) is boiled in an oil bath at 90° C. outside temperature for 22 h at the reflux. The reaction mixture is filtered hot. The filtrate is concentrated. The residue is treated with 100 ml of water. The precipitate is filtered off, washed with water and dried in air. 2.4 g of beta-carboline-3-carboxylic-acid-amide-oxime with a m.p. of 159°-163° C. is obtained.
