Procedure
A solution of 1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5-(trifluoromethyl)pyrrolo[2,3-b]pyridine, 153a, (0.551 g, 1.181 mmol), ethyl 2-(1-tert-butyl-2-(2-chloro-5-fluoropyrimidin-4-yl)hydrazinyl)ethanoate, 152a, (0.300 g, 0.984 mmol) and K3PO4 (0.627 g, 2.953 mmol) in 2-MethylTHF (26 mL) and H2O (5 mL) was degassed under a stream of nitrogen for 45 minutes. To the reaction mixture was added X-phos (0.056 g, 0.118 mmol) and Pd2(dba)3 (0.022 g, 0.025 mmol). The reaction mixture was heated at 120° C. for 75 minutes. The aqueous phase was removed and the organic phase was filtered through a pad of celite, concentrated in vacuo and purified by silica gel chromatography (30% EtOAc/Hexanes) to afford 540 mg of the desired product: 1H NMR (400 MHz, CDCl3) δ 9.49 (s, 1H), 8.71 (t, J=7.0 Hz, 1H), 8.63 (d, J=11.1 Hz, 1H), 8.16-8.11 (m, 3H), 7.31 (d, J=8.2 Hz, 2H), 7.11 (d, J=21.4 Hz, 1H), 4.10 (dd, J=13.4, 6.3 Hz, 2H), 3.79 (s, 2H), 2.39 (s, 3H), 1.24 (s, 9H), 1.17 (t, J=7.1 Hz, 3H); LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, Retention Time=4.18 minutes (M+H) 609.37.
