실험 절차

Combine 3-Methoxy-9-(4-methoxy-phenyl)-4b,5,6,7,8,8a,9,10-octahydro-phenanthrene-2-carbaldehyde (1.77 g, 5.13 mmol), carboethoxy-methylene triphenylphosphorane (03.19 g, 9.03 mmol) in toluene (53 ml) and reflux 15 hours. Remove solvent in vacuo, slurry with diethyl ether and chromatograph the residue from the concentrated filtrate on silica gel with 20% ethyl acetate/hexanes, then 25% ethyl acetate/hexanes to yield the titled compound (1.61 g, 76%). MS m/z 421(M+1).
