Reaction Conditions

Reaction Steps

To a stirred solution of 36a (340 mg, 1.1 mmol) in THF (10 mL) at -78° C. was added NaN(TMS)2 (1.0M in THF, 1.1 mL). After 15 minutes ethyl bromoacetate (250 uL, 2.2 mmol) was added and the reaction mixture to warm to -20° C. After 2 hours the reaction was quenched with HOAc (0.1 mL) and then concentrated. Flash chromatography (silica gel, 50% ethyl acetate/hexanes) gave 37a (380 mg, 90%) as an oil.
