Reaction Steps

To a solution of (S)-7-Bromo-2-{4-[2-(3-chloro-phenyl)-2-hydroxy-ethylamino]-2-oxo-1,2-dihydro-pyridin-3-yl}-3H-benzimidazole-5-carbaldehyde (130 mg, 0.27 mmol) in methanol (60 mL) was added morpholine (0.2 mL, excess). The reaction mixture was stirred 1 h at room temperature. Then NaCNBH3 (1M THF solution, 1.35 mL, 1.35 mmol) was added. The reaction mixture was stirred at room temperature overnight and concentrated in vacuo. The residue was purified by prep. HPLC to yield the title compound (68 mg, 45%). 1H NMR (400 MHz, CD3OD) δ 7.83 (1H, s), 7.69 (1H, s), 7.68 (1H, s), 7.24–7.54 (4H, m), 6.30 (1H, d, J=7.6 Hz), 4.89–5.02 (1H, m), 4.50 (2H, s), 3.66–3.71 (4H, m), 3.17–3.43 (6H, m). LCMS (M+H)+ m/z 558 (t=1.41 min.).
