Abstract

Procedure for preparing dibenzo [a, d] cycloheptene derivatives, of general formula: ** (See formula) ** in which: X represents a hydrogen or halogen atom, or an alkyl radical containing 1 to 4 carbon atoms, alkyloxy whose alkyl part contains 1 to 4 carbon atoms, alkylthio whose alkyl part contains 1 to 4 carbon atoms or trifluoromethyl; R1 and R2, identical or different, represent a hydrogen atom or an alkyl radical containing 1 to 4 carbon atoms; and R3 represents an alkyloxy radical containing from 1 to 4 carbon atoms, (dimethyl-2,2 dioxolane-1,3 yl) -4 methyloxy or a radical NR4R5 in which R4 and R5, identical or different, represent a radical alkyl containing 1 to 4 carbon atoms, hydroxyalkyl whose alkyl part contains 1 to 4 carbon or phenyl atoms, or together with the nitrogen atom to which they are attached form a 5- or 6-membered chain heterocycle containing a second heteroatoms chosen from oxygen, sulfur or nitrogen atoms, possibly substituted by an alkyl radical containing 1 to 4 carbon atoms; and optionally its addition salts with acids; characterized by reacting a product of general formula: R3 - H in which R3 is defined as above, with an acid halide of the general formula: ** (See formula) ** in which X, R1 and R2 are defined as above and Z represents a halogen atom, and then the product obtained is optionally transformed into an addition salt with an acid.
