Reaction Steps

A solution of methyl 7-(4-fluorophenyl)-7-(2-hydroxy-3,4-dimethyl-5,6,7,8-tetrahydronaphthyl)heptanoate (0.5 g) in dimethylformamide (1 ml) was added to a mixture of 60% sodium hydride (51 mg) and dimethylformamide (2 ml) at 0° C. The reaction mixture was stirred at room temperature for 30 minutes. Methyl iodide (82 ml) was added dropwise and the mixture was stirred at the same temperature for 2 hours. Water was added and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated saline and dried with anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure and the residue was subjected to silica gel column chromatography to obtain methyl 7-(4-fluorophenyl)-7-(2-methoxy-3,4-dimethyl-5,6,7,8-tetrahydronaphthyl)heptanoate (0.4 g) (Compound 58). The physical properties and spectrum data thereof are shown in Tables 3 and 4.
