الإجراء التجريبي

0.9 g (2.9 mmol) of (±)-trans-2-ethyl-4a-(3-methoxyphenyl)-7-oxo-1,2,3,4,4a,5,6,7,8,8a-decahydroisoquinoline hydrochloride (J. Med. Chem., 35, 48, 1992), 0.9 g (3.5 mmol) of N,N-diethyl-2-phenylhydrazono-3-oxobutyramide, 0.28 g (3.5 mmol) of CH3COONa, 0.87 g (13.3 mmol) of zinc dust and 5 ml of glacial acetic acid were treated as described in example 1. The residue was purified by flash chromatography (CH2Cl2 /MeOH/conc. NH4 OH 86: 10:0.6; Rf=0.27), to yield 0.2 g of the title compound.M.p.=153°-155° C. dec.
