Reaction Steps

5.2 g 6,7,8,9-tetrahydro-benzocyclohepten-5-one, 0.96 g paraformaldehyde and 10.0 g allyl-methylamine hydrochloride in 60 ml glacial acetic acid were reacted as in example 1, step 1. After analogous work-up, 6.7 g (84.8% of theoretical) 6-[(allyl-methyl-amino)-methyl]-6,7,8,9-tetrahydro-benzocyclohepten-5-one were obtained as a yellowish oil.
