Participants

Reaction Steps

CDI (0.052 g, 0.32 mmol) was added to a solution of N,N-dimethylglicine (0.033 g, 0.32 mmol) in acetonitrile (2.50 mL). The resulting solution was stirred at room temperature for 5 hours. Then 2-(2-Fluoro-5-piperazin-1-yl-phenyl)-1H-benzoimidazole (0.10 g, 0.27 mmol) and N,N-diisopropylethylamine (DIPEA) (0.11 mL, 0.6 mmol) were added and reaction was heated at 65° C. overnight. Reaction was cooled to room temperature and solvent was removed under reduced pressure. DCM (2 mL) was added to the crude, organic solution was washed with water (2×4 mL) and with saturated Na2CO3 solution (2×4 mL) and concentrated. The crude reaction mixture was purified by flash chromatography (eluent: MeOH:AcOEt gradient from 100% of AcOEt to MeOH 0.6:AcOEt 4) to afford 0.049 g of the title compound (43%).
