Versuchsvorschrift

A mixture of 1.95 g of 6,7-dihydro-5H-dibenz[c,e]azepine and 3 g of urea is stirred at 120° C. for 15 minutes and then poured onto ice/water. After extracting the resulting aqueous mixture with methylene chloride the combined extracts are washed with water, dried over anhydrous sodium sulphate and evaporated. The solid residue is recrystallized from n-hexane/ethyl acetate, and in this manner there is obtained pure 5,7-dihydro-6H-dibenz[c,e]azepine-6-carboxamide, m.p. 212°-214° C.
