Procedure

To 1H-Pyrrolo[2,3-b]pyridine (1, 0.100 g, 0.846 mmol) and 5-chloro-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde (100, 0.205 g, 0.931 mmol) was added 2 mL of methanol to give a solution. Potassium hydroxide (0.0475 g, 0.846 mmol) was added and the reaction was allowed to stir at room temperature for 48 hours. The reaction was extracted with ethyl acetate and water. The organic layer was dried over anhydrous magnesium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with a gradient of 0-5% methanol in dichloromethane to give the compound (P-0079, 32 mg, 11%). MS (ESI) [M+H+]+=353.2.
