摘要

Procedure for the preparation of N N'- (isopropyl-malonyl) -5 6-dihydro-benzo (c) cinoline and its salts characterized in that a compound of general formula ** (see formula) ** is reacted in which R1 and R2 represent hydrogen, an alkali metal or an acyl radical with compounds capable of replacing radicals R1 and R2 directly or in stages by the divalent radical of formula and because N N'- (isopropyl-malonyl) 5 6-dihydro-benzo is eventually transformed (c) cinolin obtained in one of its salts with a base.
