To a solution of (S)-4-(1-hydroxymethyl-2-phenyl-ethylamino)-3-(4-methyl-6-piperazin-1-yl-1H-benzimidazol-2-yl)-1H-pyridin-2-one (30 mg, 0.063 mmol) in methanol (2 mL) was added benzoyl chloride (1 drop). The reaction mixture was stirred for 5 min. and concentrated. The residue was purified by prep. HPLC to yield the title compound (11 mg, 33%). 1H NMR (400 MHz, CD3OD) δ 7.48–7.54 (5H, m), 7.37 (1H, s), 7.13–7.26 (7H, m), 6.08 (1H, d, J=7.7 Hz), 3.79–4.02 (5H, m), 3.76 (1H, dd, J=4.7, 11.2 Hz), 3.67 (1H, dd, J=5.7, 11.2 Hz), 3.54 (4H, m), 3.03 (1H, dd, J=5.7, 13.7 Hz), 2.89 (1H, dd, J=8.0, 13.7 Hz), 2.62 (3H, s). LCMS (M+H)+ m/z 563 (t=2.19 min.).
