Abstract

5-carbaoyl-10-oxo- 10,11-dihydro-5H-dibenz(b,f)azepine of general formula (I) is prepd. from 5-carbamoyl-10-methoxy-5H-dibenz(b ,f)-azepine of general formula (IV). Cpd. (IV) is obtd. by chloro-carbonylation of 10-methoxy-5H-dibenz(b,f)azepine of general formula (II) with chloro-formic-acid-trichloromethyl-ester, to obtain 5-chloro-carbonyl-10-methoxy-5H-di:benz(b,f)azepine (III). Without isolating (III) or disturbing the reaction mixt., (IV) is obtd.by ammonolysis in the mixt.
