Abstract
Process for obtaining dibenzocycloheptenes, and especially 5- (3-methylaminopropyl) -5H-dibenzo [a, d] cycloheptene, which comprises the reaction of a compound of the formula, ** (See formula) ** where M is sodium, potassium or lithium, with a compound of formula ** (See formula) ** where X is a halogen or -O-SO2-R '; R 'is an alkyl, cycloalkyl, aryl or aralkyl group; And it is (see formula) or -SO2-; R2 is an alkyl, aryl group; cycloalkyl or aralkyl, and may also be hydrogen or an alkoxy, aryloxy, aralkoxy or cycloalkoxy group if Y is (see formula), to form a compound of formula ** (See formula) ** where Y and R are as stated; and the conversion of the latter to 5- (3-methylaminopropyl) -5H-dibenzo [a, d] cycloheptene, by hydrolysis or by reductive or hydrolytic dissociation.
