Procedure

To 3-(3-Benzyloxy-2,6-difluoro-benzyl)-5-pyridin-3-yl-1H-pyrrolo[2,3-b]pyridine (P-1455, 700.0 mg, 1.64 mmol, prepared as described in Example 24, Scheme 43a) in tetrahydrofuran (40.0 mL) was added sodium hydride (60% in mineral oil, 100.0 mg, 2.5 mmol). After 10 minutes, triisopropylsilyl chloride (0.60 mL, 0.0028 mol) was added to the reaction. The reaction was stirred at room temperature for 2 hours. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 20% ethyl acetate in hexane to give the compound as colorless oil (548, 0.85 g, 89%).
