Procedure
To a -5° C. solution of the aldehyde from Step 2 (3.00 g, 24.4 mmol) in 65 mL of THF was added methyl magnesium chloride (3.0M solution in THF, 9.5 mL, 29 mmol) and the reaction was stirred 2 h at 0° C. The reaction was quenched with 1M HCl and extracted with ethyl acetate. The organic extracts were washed with saturated NaHCO3 and brine and dried over MgSO4. Purification by flash chromatography (30% ethyl acetate/hexanes) provided 2.46 g of the title product.
