Procedure

A mixture of N-benzyl-(3-methoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)amine (0.30 g) and (R)-3-chlorophenyl oxirane (0.18 g) in ethanol (0.6 ml) was refluxed overnight. The reaction mixture was evaporated in vacuo, and the residue was purified by column chromatography on silica gel eluting with a mixture of hexane and ethyl acetate (5:1). The product (0.43 g) was treated with 4N hydrogen chloride in ethyl acetate and powdered from diisopropyl ether to afford (1R)-2-[N-benzyl-N-(3-methoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)amino]-1-(3-chlorophenyl)ethanol (0.40 g).
