Reaction Steps

To the THF solution of the above Compound 25 was slowly added 1.4 eq of methylmagnesium bromide at room temperature. The reaction mixture was stirred at r.t. for 1 h. To the reaction mixture was added ethyl acetate and 1N HCl. The organic phase was washed with brine and dried over magnesium sulfate. The solvent was removed under reduced pressure, and the crude product, obtained in 96% yield, was used directly for the next step without purification.
