To 5-bromo-7-azaindole (44, 198.0 mg, 1.01 mmol) in methanol (30.0 mL, 0.741 mol) were added (4-Chloro-benzyl)-(5-formyl-pyridin-2-yl)-carbamic acid tert-butyl ester (43, 355.0 mg, 1.02 mmol) and potassium hydroxide (80.0 mg, 1.42 mmol). The reaction was stirred at room temperature 48 hours. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, concentrated and purified by silica gel column chromatography eluting with 8% methanol in dichloromethane to give compound (45, 200.0 mg, 36.8%).
