Reaction Steps

3.24 g (10 mmol) of (±)-trans-2-ethyl-4a-(3-methoxyphenyl)-6-oxo-1,2,3,4,4a,5,6,7,8,8a-decahydroisoquinoline hydrochloride, 6.16 g (30.0 mmol) of 2-phenylhydrazono-3-oxobutyramide, 2.46 g (7.0 mmol) of CH3COONa, 7.85 g (120.0 mmol) of zinc dust and 15 ml of glacial acetic acid were treated as described in example 1. The residue was purified by chromatography on silica gel (Et2O-EtOAc/MeOH 0%→50%) yielding 3.0 g of oily product which was triturated in Et2O yielding 2.5 g of the title compound. M.p.=176°-178° C.
