Abstract

Procedure for the production of derivatives of benzocycloheptathiophene, of formula I **(See formula)** where R1 is hydrogen, chlorine, bromine or alkoxy of 1 to 4 carbon atoms, R2 is hydrogen, each of R3 and R4 is hydrogen or methyl, R5 is alkyl of 1 to 4 carbon atoms, or R5 together with R2 is an ethylenic chain, or R5 together with R3 is an ethylene or trimethylene chain, or R5 together with R4 is a trimethylene or tetramethylene chain, and R6 is alkyl of 1 to 4 carbon atoms, characterized in that it is a compound of formula II, **(See formula)** where R1 to R6 have the meanings indicated above, and X is chlorine or bromine in position 9 or 10 of the structure (see formula), with a strong, aqueous, non-oxidizing acid, such as sulfuric, hydrochloric, hydrobromic, phosphoric, methanesulfonic, toluenesulfonic, trifluoroacetic, and trichloroacetic acids, preferably in an aqueous solution, preferably at a temperature between 60º and 230ºC, preferably at a pressure between 1 and 21 atmospheres and preferably at an acid concentration between 2.5 and 70%, particularly between 20 and 70%.
