Reaction Steps

To a stirred solution of N-(4-fluoro-2-methoxy-5-nitro-phenyl)-4-(1-methylindol-3-yl)pyrimidin-2-amine (Intermediate 176, 65 g, 160.28 mmol) and N,N′,N′-trimethylethane-1,2-diamine (19.65 g, 192.3 mmol) in DMA (630 mL) was added N-ethyl-N-isopropyl-propan-2-amine (26.93 g, 208.4 mmol) at r.t. The resulting mixture was stirred at 85° C. for 5-6 h then cooled to r.t. Water (630 mL) was then added and the mixture was stirred for 3-4 h. Solid material was collected by filtration, washed with water (315 mL) and dried at 50° C. for 12 h to give the title compound (79.4 g, 96%) as orange solid; 1H NMR (CDCl3): 2.29 (6H, s) 2.60 (2H, t), 2.93 (3H, s), 3.31 (2H, t), 3.96 (3H, s), 4.00 (3H, s), 6.69 (1H, s), 7.21 (1H, d), 7.30-7.38 (2H, m), 7.43 (1H, d), 7.56 (1H, s), 8.18 (1H, d), 8.30 (1H, s), 8.41 (1H, d), 9.59 (1H, s); m/z: ES+ MH+ 476.23.
