Under nitrogen, a solution of 0.19 g of 9-acetyl-5-bromoethyl-beta-carboline-3-carboxylic acid ethyl ester in 5 ml of ethanol is mixed with 1 ml of morpholine and stirred overnight at room temperature. After addition of water the crystallizate is suctioned off and recrystallized from ethanol/diethylether. 0.11 g (64%) is obtained. Melting point 285° C.
