A mixture of (S)-1-(1-benzyl-6-fluoro-1H-benzoimidazol-2-yl)ethylamine (320 mg, 1.19 mmol), 4-amino-6-chloropyrimidine-5-carbonitrile (184 mg, 1.19 mmol) and DIPEA (1.06 mL, 5.95 mmol) in IPA (5 mL) was heated at 90° C. in a sealed vial overnight. The resultant mixture was allowed to cool to RT and then concentrated in vacuo. The residue was purified by column chromatography (silica gel, gradient 0-10% [2M NH3 in MeOH] in DCM) to afford 394 as a white solid (164 mg, 36%). LCMS (Method K): RT 3.58 min [M+H]+ 388.1 1H NMR (DMSO-d6, 400 MHz): δ 7.94 (1H, s), 7.69 (1H, d, J=7.9 Hz), 7.61 (1H, dd, J=8.9, 4.5 Hz), 7.13-7.28 (5H, m), 6.95-7.05 (3H, m), 5.65 (1H, qn, J=7.9 Hz), 5.46 (2H, q, J=9.91, 5.5 Hz), 3.12 (1H, d, J=5.5 Hz), 1.49 (3H, d, J=6.77 Hz)
