A mixture of (S)-1-(6-fluoro-1-phenyl-1H-benzoimidazol-2-yl)propylamine (62 mg, 0.23 mmol), 4-amino-6-chloro-5-cyanopyrimidine (36 mg, 0.23 mmol) and DIPEA (0.08 mL, 0.46 mmol) in IPA (2 mL) was heated for 6 h at 90° C. After cooling to RT, the volatiles were removed in vacuo and the resulting residue was purified by column chromatography (Si—PPC, gradient 0-5% 2M NH3/MeOH in EtOAc) to afford 358 as a white solid (70 mg, 79%). LCMS (Method K): RT 4.10 min [M+H]+ 388.1. 1H NMR (DMSO-d6, 400 MHz): δ 7.81 (1H, s), 7.68 (1H, dd, J=8.8, 4.9 Hz), 7.56-7.44 (6H, m), 7.16 (2H, br s), 7.07 (1H, ddd, J=9.8, 8.8, 2.5), 6.79 (1H, dd, J=8.9, 2.5), 5.29 (1H, dt, J=7.7, 6.2), 1.97 (1H, dqd, J=14.9, 7.5, 6.2), 1.87 (1H, dqd, J=14.9, 7.5, 6.2), 0.75 (3H, t, J=7.5)
