Reaction Steps

A mixture of ethyl 2-ethoxy-3-(4-hydroxyphenyl)-propionate (2.38 g, 0.01 mol), 5-(2-bromo-1-ethylidene)-10,11-dihydro-5H-dibenzo[a,d]cycloheptene (2.75 g, 0.01 mol) and potassium carbonate (5.14 g, 0.03 mol) in dimethylformamide (30 ml) was heated at 100° C. for 20 h. The reaction mixture was diluted with benzene (80 ml), washed with 5% aqueous citric acid (3×25 ml) and with saturated NaHCO3 (25 ml), dried (MgSO4) and evaporated. The residue (4.88 g) was purified by column chromatography on silica gel (benzene eluent) to yield the title compound; 2.3 g (53.7%).
