Procedure

To [6-Methoxy-5-(1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-pyridin-2-yl]-(4-trifluoromethyl-benzyl)-amine (31, 0.0340 g, 0.0598 mmol) was added tetrahydrofuran (5 mL) followed by tetra-n-butylammonium fluoride (1M solution in tetrahydrofuran, 66 μL, 0.0658 mmol). The reaction was allowed to stir at room temperature for 2 hours, then poured into 1:1 water:saturated sodium bicarbonate and extracted with ethyl acetate. The organic layer was separated, dried over magnesium sulfate, filtered and the volatiles were removed by rotary evaporation. The resulting residue was purified by silica gel column chromatography, eluting with dichloromethane followed by 1% methanol in dichloromethane and finally 3% methanol in dichloromethane. This provided 20 mg of the desired compound as a white solid (P-0012, 0.048 mmol, 81%). MS (ESI) [M+H+]+=413.2.
