To a solution of (4-(3-(azetidin-3-yl)pyridin-2-yloxy)phenyl)(1H-benzo[d]imidazol-2-yl)methanone (279 mg, 0.753 mmol) in DMF (1.0 mL) is added triethylamine (0.386 mL, 3.01 mmol) and 1-(1H-imidazol-1-yl)ethanone (100 mg, 0.904 mmol). A solid crashed out, so THF (2 mL) was added to give a homogeneous solution and the reaction was stirred at rt 2 h. The reaction mixture was quenched with saturated NaHCO3 and extracted with CH2Cl2 (3×5 mL). The combined organic layers were dried (MgSO4) and concentrated, then purified by RPHPLC to give 1-(3-(2-(4-(1H-benzo[d]imidazole-2-carbonyl)phenoxy)pyridin-3-yl)azetidin-1-yl)ethanone (35 mg, 0.085 mmol, 11.27% yield over 2 steps) as a white solid. MS (ESI, pos. ion) m/z: 413.0 (M+1). IC50 (uM) +++++.
