Zusammenfassung:1419682 Aminoalkyl in dibenzocyclohepten-5- ones SANDOZ Ltd 5 Feb 1973 [7 Feb 1972 20 Nov 1972] 28237/75 Divided out of 1419681 Heading C2C Novel compounds of the formula (VI) wherein R 1 is H, C 1-3 alkyl or alkoxy, or F; R 2 is H, C 1-3 alkyl or alkoxy, F or CF 3 and R 3 and R 4 independently signify C 1-3 alkyl groups, may be obtained by cyclizing a compound of Formula (X) in which A denotes OH, Cl or straight chain C 1-4 alkoxy, preferably in the presence of a strong Lewis acid or strong mineral acid. Intermediates X are obtained by reducing a compound of Formula XI
