Reaction Steps

A mixture of intermediate (5-a) (0.03 mol) and benzenemethanamine (0.073 mol) in 2,2'-oxybispropane (250 ml) and N,N-dimethylacetamide (10 ml) was hydrogenated with palladium on activated carbon (10%) (1 g) as a catalyst. After uptake of hydrogen (1 eq.), the catalyst was filtered off. The filtrate was evaporated. The residue was stirred in a mixture of water and 1,1'-oxybisethane. The organic layer was separated, dried (MgSO4), filtered and the solvent was evaporated, yielding 6.5 g of (±)-2,3,4,7,8,9-hexahydro-N-(phenylmethyl)cyclopenta[h]-1-benzopyran-2-methanamine (interm. 14-a).
