A solution of 3-amino-5-nitrobenzonitrile (3.59 g, 22 mmol) in CH3CN (10 mL) was added dropwise to a mixture of 5-(chloromethyl)-N-isopropyl-2-(methylthio)pyrimidin-4-amine from Example A9 (5 g, 22 mmol), sodium iodide (0.33 g, 2.2 mmol), and diisopropylethylamine (2 mL, 12 mmol) in CH3CN (100 mL) at 0° C. The resultant reaction mixture was stirred at RT overnight. The solvent was evaporated and the residue was diluted with water, and extracted with EtOAc. The combined organics were washed with brine, dried (MgSO4), concentrated and purified by silica gel chromatography to afford 3-((4-(isopropylamino)-2-(methylthio)pyrimidin-5-yl)methylamino)-5-nitrobenzonitrile (2.2 g, 28% yield). 1H NMR (400 MHz, DMSO-d6): δ 7.87 (s, 1 H), 7.74 (s, 1 H), 7.56 (s, 1 H), 7.32 (s, 1H), 7.08 (m, 1 H), 6.63 (d, J=7.6 Hz, 1 H), 4.30 (m, 1 H), 4.15 (s, 2 H), 2.50 (s, 3 H), 1.17-1.15 (d, J=6.4 Hz, 6 H); MS (ESI) m/z: 359.2[M+H]+.
