Procedure

To a solution of EXAMPLE 377B (0.750 g) in N,N-dimethylformamide (5 mL) was added sodium hydride (0.091 g). The reaction was stirred for 30 minutes at room temperature and then iodomethane (0.142 mL) was added to the reaction and stirring was continued at room temperature for 2 hours. The reaction was quenched with water (25 mL) and extracted with ethyl acetate (75 mL). The organic layer was separated, washed with brine (50 mL), dried over magnesium sulfate, filtered, and concentrated. The residue was loaded onto silica gel (Reveleris 40 g) and eluted with a gradient of 5-15% ethyl acetate/hexanes over 30 minutes (flow=40 ml/min) to provide the title compound.
