실험 절차

A mixture of (5-Formyl-pyridin-2-yl)-(4-trifluoromethyl-benzyl)-carbamic acid tert-butyl ester (19, 41 mg, 0.11 mmol, prepared as described in Example 30), 5-triisopropylsilanyloxy-1H-pyrrolo[2,3-b]pyridine (83, 34 mg, 0.12 mmol) and potassium hydroxide (9.8 mg, 0.17 mmol) in methanol (10 mL) was stirred at room temperature overnight. The reaction mixture was poured into water, extracted with ethyl acetate, washed with 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 (84, 0.05 g, 70%). MS (ESI) [M+H+]+=671.38.
