Procedure

A mixture of N′-[5-chloro-4-(1-methylindol-3-yl)pyrimidin-2-yl]-4-methoxy-6-(4-methylpiperazin-1-yl)benzene-1,3-diamine (Intermediate 91, 344 mg, 0.72 mmol), zinc powder (4.71 mg, 0.07 mmol), tris(dibenzylideneacetone)dipalladium(0) (65.9 mg, 0.07 mmol), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine (‘XPhos’, 68.6 mg, 0.14 mmol), and dicyanozinc (50.7 mg, 0.43 mmol) were placed in a reaction tube under N2 and then degassed DMA (1.91 mL) was added. The resulting suspension was shirred at 95° C. for 2 h. The mixture was then diluted with EtOAc and washed 5 times with water, and then with brine. The solution was then dried (MgSO4) and concentrated in vacuo. The residue was dissolved in CH3OH and 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 and the resulting residue was triturated with diethyl ether. The resulting solid was collected by filtration and washed with diethyl ether to give the title compound (208 mg, 62%) as a yellow solid; 1H NMR: 2.28 (3H, s), 2.51-2.58 (4H, m), 2.89-2.95 (4H, m), 3.69 (3H, s), 3.91 (3H, s), 4.23 (2H, br s), 6.75 (1H, s), 7.08 (1H, s), 7.09-7.12 (1H, m), 7.26 (1H, ddd), 7.50 (1H, d), 8.31 (1H, d), 8.43 (1H, s), 8.61 (1H, s), 8.64 (1H, s); m/z: ES+ MH+ 469.33.
