Procedure

To a solution of 2-(1,2-dihydroxy-1-methyl-ethyl)-6-trifluoromethyl-1-H-indole-5-carbonitrile (209.6 mg, 0.7374 mmol) in dry DMF (4 ml) was added NaH (60 mg, 1.4749 mmol, 60% in mineral oil). After the reaction mixture was stirred at room temperature for 30 min., 4-fluorobenzonitrile (98.15 mg, 0.8115 mmol) was added, and the reaction mixture stirred at room temperature. After HPLC indicated the consumption of starting material, the reaction mixture was poured onto water and extracted with ethyl acetate. The organic layer was washed with 10% LiCl, brine and dried over MgSO4. Column chromatography (EtOAc/Hexanes 50%-100%) yielded the title product as a light yellow powder.
