To a solution of [2-((S)-1-aminoethyl)-5-fluoro-3-phenyl-3H-benzoimidazol-4-yl]methanol dihydrochloride (159 mg, 0.45 mmol) in IPA (5 mL) was added 4-amino-6-chloropyrimidine-5-carbonitrile (69 mg, 0.45 mmol) and DIPEA (228 μL, 1.33 mmol) and the reaction mixture heated at 80° C. for 16 h. The reaction mixture was concentrated in vacuo and the resultant residue purified by prep HPLC (C18 phenomenex column, 10-90% MeCN in water 0.1% formic acid, 20 min gradient) to give 353 as a white solid (87 mg, 49%). 1H NMR 400 MHz δ (d6-DMSO): 7.78 (1H, s), 7.65-7.56 (2H, m), 7.55-7.38 (5H, m), 7.16 (2H, br s), 7.05 (1H, dd, J=10.6, 8.8 Hz), 5.15 (1H, quin, J=6.9 Hz), 4.51 (1H, t, J=5.0 Hz), 3.97 (2H, d, J=5.0 Hz), 1.43 (3H, d, J=6.9 Hz)
