Participants

Reaction Steps

A solution of EXAMPLE 157B (0.62 g) was dissolved in N,N-dimethylformamide (10 mL) and treated with NaH (0.062 g, 60% in mineral oil). After 10 minutes, iodomethane (0.16 mL) was added. After 1 hour, additional sodium hydride (0.5 eq.) and iodomethane (0.5 eq.) were added and stirring was continued at room temperature for 3 hours. The reaction was diluted with ether (75 mL) and washed with water (50 mL) and brine (50 mL), dried over magnesium sulfate, filtered, and concentrated. Silica gel chromatography eluting with a gradient of 1.5% to 15% ethyl acetate/hexanes provided the title compound.
