Reaction Steps

To a solution of ethyl 2-[tert-butyl-[[5-fluoro-2-[5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl]pyrimidin-4-yl]amino]amino]acetate, 155a, (0.200 g, 0.440 mmol) in THF (40 mL) was added a solution of lithium hydroxide hydrate (0.074 g, 1.760 mmol) in H2O (4 mL). The reaction mixture was stirred at room temperature overnight. The reaction mixture concentrated in vacuo to remove the THF. The remaining aqueous phase was diluted to 8 mL and the solution was used directly in a preparatory HPLC. The product precipitated when the fraction was concentrated on rotavaporator. The solid was filtered and dried in desiccator with P2O5 to afford 120 mg of the desired product: 1H NMR (400 MHz, d6-DMSO) δ 12.65 (s, 1H), 12.41 (s, 1H), 9.28 (s, 1H), 8.86 (s, 1H), 8.65 (s, 1H), 8.30 (d, J=3.5 Hz, 2H), 3.97-3.70 (m, 1H), 3.51 (s, 1H), 1.18 (s, 9H); LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, Retention Time=2.92 min, (M+H) 427.40
