Procedure

DIPEA (0.411 mL, 2.36 mmol) was added to a suspension of N-(4-fluoro-2-methoxy-5-nitrophenyl)-4-(1-methylindol-3-yl)pyrimidin-2-amine (Intermediate 129, 425 mg, 0.94 mmol) and (3aR,6aR)-5-methyl-2,3,3a,4,6,6a-hexahydro-1H-pyrrolo[3,4-b]pyrrole (Intermediate 37, 250 mg, 1.98 mmol) in 2,2,2-trifluoroethanol (4 mL). The mixture was heated in a microwave at 140° C. for 1 h. The cooled mixture was then purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M methanolic ammonia and concentrated in vacuo. Further purification by FCC, eluting with 0-5% 7N methanolic ammonia in CH2Cl2 gave impure title compound (396 mg, 84%) as an orange/red solid. This solid was dissolved in the minimum amount of CH2Cl2 and the resulting solution was triturated with methanol. The resulting solid was collected by filtration to give the title compound (272 mg, 58%) as a red solid which was used without further purification; 1H NMR: 1.86 (1H, dd), 1.94-2.06 (1H, m), 2.12 (3H, s), 2.23 (1H, dd), 2.36-2.45 (2H, m), 2.52-2.58 (1H, m) partially obscured by DMSO peak, 2.91-3.04 (1H, m), 3.18 (1H, t), 3.49 (1H, td), 3.87 (3H, s), 3.95 (3H, s), 4.40 (1H, t), 6.61 (1H, s), 7.11 (1H, t), 7.18 (1H, d), 7.24 (1H, t), 7.51 (1H, d), 8.02 (1H, s), 8.27-8.31 (2H, m), 8.34 (1H, d), 8.51 (1H, s); m/z: ES+ MH+ 500.17.
