Reaction Conditions

Reaction Steps

A solution of methyltriphenylphosphonium bromide (0.33 g, 0.923 mmol) in THF (2.5 mL) was treated with a solution of potassium tert-butoxide in THF (0.89 mL, 1 M) dropwise, stirred for 1 hour at 25° C., treated with a solution of the product from Example 117A (0.116 g, 0.298 mmol) in THF (2 mL), stirred at 25° C. for 16 hours, quenched with saturated ammonium chloride solution and partitioned between ethyl acetate and water. The organic phase was washed with brine and dried over MgSO4, filtered and concentrated. The residue was chromatographed on silica gel eluting with 15%-25% ethyl acetate in hexane to give the title compound (0.040 g, 35% yield).
