Procedure

A solution of (+/-)-Trans-1,3,4,5-tetrahydro-3-(methoxycarbonyl)-4-(3,4-methylenedioxyphenyl)-2H-1-benzazepine-2-one (0.35 g, 1.03 mmol) in DMF (3 ml) was added to a mixture of sodium hydride (0.036 g, 1.2 mmol, 80% mineral oil dispersion) and the mixture stirred 1 h at ambient temperature. Methyl iodide (0.4 ml, 0.91 g, 6.43 mmol) in DMF (0.5 ml) was added and the mixture stirred 48 h at ambient temperature. The reaction was quenched in water (50 ml) and extracted with ethyl acetate (3×10 ml). The combined extracts were dried (MgSO4), filtered and the solvent removed at reduced pressure to give 0.40 g of crude product. Chromatography on silica gel with 30:70 ethyl acetate-hexane gave 0.335 g of the title compound as a viscous oil. The oil was treated with hexane and the resulting white solid collected and dried to give 0.226 g (62%) of the title compound; mp 125°-127°.
