実験手順

A mixture of {5-[hydroxy-(5-triisopropylsilanyloxy-1H-pyrrolo[2,3-b]pyridin-3-yl)-methyl]-pyridin-2-yl}-(4-trifluoromethyl-benzyl)-carbamic acid tert-butyl ester (84, 0.05 g, 0.07 mmol), trifluoroacetic acid (0.5 mL, 0.006 mol), and triethylsilane (1 mL, 0.006 mol) in acetonitrile (10 mL) was refluxed for 2 hours. The reaction mixture was poured into ice water, extracted with ethyl acetate, washed with saturated sodium bicarbonate, brine, and dried over sodium sulfate. After removal of solvent, the residue was purified by silica gel column chromatography eluting with ethyl acetate in hexane to provide the compound as a viscous liquid (85, 0.04 g, 97%). MS (ESI) [M+H+]+=555.38.
