Potassium Hydroxide → (5-(Hydroxy-[5-(2-morpholin-4-yl-ethoxy)-1H-pyrrolo[2,3-b]pyridin-3-yl]-methyl}-pyridin-2-yl)-(4-trifluoromethyl-benzyl)-carbamic acid tert-butyl ester

Participants

Reaction Steps

A mixture of (5-Formyl-pyridin-2-yl)-(4-trifluoromethyl-benzyl)-carbamic acid tert-butyl ester (23, 315 mg, 0.828 mmol), 5-(2-morpholin-4-yl-ethoxy)-1-pyrrolo[2,3-b]pyridine (20, 205 mg, 0.829 mmol, prepared as described in Example 14), and potassium hydroxide (70 mg, 1 mmol) in methanol (25 mL) was stirred at room temperature overnight. The reaction mixture was poured into ice 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 methanol in dichloromethane to provide the compound as a yellow solid (24, 0.2 g, 40%). MS (ESI) [M+H+]+=628.42.
