Procedure

A mixture of N′-(5-chloro-4-pyrazolo[1,5-a]pyridin-3-ylpyrimidin-2-yl)-4-methoxy-6-(4-methylpiperazin-1-yl)benzene-1,3-diamine (Intermediate 63, 157 mg, 0.34 mmol), zinc (2.209 mg, 0.03 mmol), tris(dibenzylideneacetone)dipalladium(0) (30.9 mg, 0.03 mmol), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine (‘XPhos’, 32.2 mg, 0.07 mmol), and dicyanozinc (23.8 mg, 0.20 mmol) were placed in a reaction tube under N2 and then degassed DMA (0.9 mL) was added. The resulting suspension was stirred to 95° C. for 1.5 h. The mixture was then diluted with EtOAc and washed five times with water, then brine. The solution was then dried (MgSO4) and concentrated in vacuo. The residue was triturated with diethyl ether and the resulting solid was collected by filtration, and washed with diethyl ether. The solid was then dissolved in a mixture of CH2Cl2 and CH3OH and the solution was allowed to pass through a stratospheres SPE cartridge PL-Thiol MP SPE (available from Polymer Laboratories) under gravity. The resulting solution was concentrated in vacuo to give the title compound (87 mg, 57%) as a yellow solid; 1H NMR: (100° C.) 2.28 (3H, s), 2.49-2.58 (4H, m), 2.90-2.98 (4H, m), 3.70 (3H, s), 4.28 (2H, br s), 6.77 (1H, s), 6.99 (1H, s), 7.14 (1H, t), 7.37 (1H, t), 8.37 (1H, d), 8.55 (1H, s), 8.78 (1H, d), 8.85 (1H, s), 8.92 (1H, s); m/z: ES+ MH+ 456.4.
