Participants

Reaction Steps

To 3-((5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)(methoxy)methyl)-1H-pyrrolo[2,3-b]pyridine (P-0079, 0.030 g, 0.085 mmol) was added acetonitrile (10 mL, 0.2 mol). Trifluoroacetic acid (500 uL, 0.006 mol) and triethylsilane (500 uL, 0.003 mol) were added and the reaction allowed to stir at room temperature for 16 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 dichloromethane followed 5% methanol in dichloromethane to give the compound as a yellowish foam (P-0080, 29 mg, 98%).
