To a solution of [2-((S)-1-aminoethyl)-5-fluoro-3-phenyl-3H-benzoimidazol-4-yl]acetonitrile dihydrochloride (100 mg, 0.27 mmol) in IPA (2 mL) was added 4-amino-6-chloropyrimidine-5-carbonitrile (44 mg, 0.28 mmol) and DIPEA (139 μL, 0.82 mmol) and the reaction mixture heated at 90° 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 345 as a white solid (119 mg, 66%). 1H NMR 400 MHz δ (d6-DMSO): 7.73 (1H, dd, J=8.8, 4.8 Hz), 7.67 (1H, d, J=7.2 Hz), 7.63-7.58 (1H, m), 7.56-7.45 (4H, m), 7.18 (1H, dd, J=10.6, 8.8 Hz), 7.14 (2H, br s), 5.22 (1H, quin, J=5.2 Hz), 3.38-3.21 (2H, m), 1.47 (3H, d, J=6.8 Hz), LCMS (Method K): RT=3.56 min, [M+H]+=413
