Procedure

To a solution of ethyl 2-(1-tert-butyl-2-(5-fluoro-2-(1-tosyl-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-yl)hydrazinyl)ethanoate, 154a, (0.54 g, 0.89 mmol) in THF (20 mL) was added tetrabutylammonium fluoride (1.78 mL of 1 M, 1.78 mmol). The reaction mixture was stirred at room temperature for 30 minutes. The reaction mixture was diluted into EtOAc and brine. The organic phase was dried over MgSO4, filtered and concentrated in vacuo. The resulting residue was purified via silica gel chromatography (70% EtOAc/Hexanes) to afford 300 mg of the desired product. 1H NMR (400 MHz, CDCl3) δ 10.59 (s, 1H), 9.55 (s, 1H), 8.66 (s, 1H), 8.29 (d, J=2.2 Hz, 1H), 8.13 (dd, J=3.8, 1.5 Hz, 1H), 7.14 (s, 1H), 4.20-4.04 (m, 2H), 3.85 (s, 2H), 1.28 (d, J=9.1 Hz, 9H), 1.19 (dt, J=7.1, 3.6 Hz, 3H). LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, Retention Time=2.93 min, (M+H) 455.43.
