To (4-Trifluoromethyl-benzyl)-[5-(5-triisopropylsilanyloxy-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-pyridin-2-yl]-amine (85, 0.13 g, 0.23 mmol) in tetrahydrofuran (10 mL) was added tetrabutylammonium fluoride (3 mL, 1.0 M in tetrahydrofuran, 3 mmol). The reaction mixture was stirred at room temperature overnight, and then was stirred at 65° C. for 48 hours. The reaction mixture was concentrated and purified by silica gel column chromatography eluting with ethyl acetate in hexane to provide the compound as a viscous liquid (P-0061, 0.062 g, 66%). MS (ESI) [M+H+]+=399.19.
