Procedure

Compound 98 (354 mg, 0.989 mmol) was dissolved in THF (5 mL), and a diethyl ether solution of 3 mol/L phenylmagnesium bromide (1.32 mL, 3.96 mmol) was added thereto under ice-cooling, followed by stirring at room temperature for 1 hour. A saturated aqueous solution of ammonium chloride was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was reslurried with ethanol to afford the entitled Compound 99 (220 mg, 59%) as pale yellow crystals.
