Procedure

To a microwave vessel was added 4-amino-6-chloropyrimidine-5-carbonitrile (0.075 g, 0.486 mmol), DIEA (0.162 mL, 0.926 mmol), and 1-(6-fluoro-1-(5-fluoropyridin-3-yl)-1H-benzo[d]imidazol-2-yl)ethanamine (0.127 g, 0.463 mmol) in n-butanol (2.315 mL). The solution was stirred at 120° C. for 4 h under microwave irradiation and then purified by column chromatography on a silica gel column using 0 to 10% gradient of MeOH in DCM as eluent to give 4-amino-6-((1-(6-fluoro-1-(5-fluoro-3-pyridinyl)-1H-benzimidazol-2-yl)ethyl)amino)-5-pyrimidinecarbonitrile: 1H NMR (400 MHz, DMSO-d6) δ ppm 1.59 (d, J=6.85 Hz, 3H) 5.60 (qd, J=7.04, 6.85 Hz, 1H) 7.08 (dd, J=9.00, 2.35 Hz, 1H) 7.15 (td, J=9.78, 8.90, 2.45 Hz, 1H) 7.25 (br. s., 2H) 7.69-7.81 (m, 2H) 7.84 (s, 1H) 8.08 (d, J=9.00 Hz, 1H) 8.63 (s, 1H) 8.67 (d, J=2.54 Hz, 1H); LC-MS (ESI) m/z 393.0 [M+H]+.
