Procedure

(6-Ethoxy-pyridin-3-yl)-{6-fluoro-5-[hydroxy-(5-methyl-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methyl]-pyridin-2-yl}-carbamic acid tert-butyl ester (70, 0.400 g, 0.616 mmol) is alternatively dissolved in 11.8 mL of dichloromethane, and Dess-Martin periodinane (0.100 g, 0.236 mmol) is added. The reaction is stirred at room temperature for 30 minutes, then concentrated under vacuum. The resulting material is purified by silica gel column chromatography, eluting with 20-100% ethyl acetate in hexane. Appropriate fraction are combined and concentrated under vacuum to provide the desired compound (71, 0.200 g).
