Procedure

[5-(3-Chloro-benzylamino)-2-methyl-2H-pyrazol-3-yl]-(5-chloro-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methanol (649, 0.033 g, 0.059 mmol) was combined with dichloromethane (5 mL, 0.08 mol) and triethylsilane (200 μL, 1.0 mmol) was added, followed by trifluoroacetic acid (100 μL, 1.0 mmol). The reaction was stirred at room temperature overnight and then concentrated. Ethyl acetate was added and the organic portion was washed with 1 M potassium carbonate, dried over anhydrous sodium sulfate and concentrated. Purification with silica gel flash chromatography eluting with a gradient of methanol (2-20%) and dichloromethane followed by washes with a mixture of ethyl acetate:hexane gave the desired compound (P-0410, 0.0039 g, 17%). (ESI) [M+H+]+=387.30.
