Reaction Steps

2,3-Difluoro-N-butyl-N-[(4-chlorobut-2-enyl)-1H-benzoimidazol-2-ylmethyl)-benzamide (26 mg, 0.06 mmol) was dissolved in 0.3 mL toluene. Piperidine (10 μL, 0.1 mmol) dissolved in 0.5 mL 95/5 toluene/4-methylmorpholine was added and the reaction mixture was heated at 90° C. for 15 hours. The reaction mixture was cooled to room temperature and deposited on a 1 g silica SPE column. The column was washed with 4 mL ethyl acetate to remove impurities followed by 4 mL 10/2/1 ethyl acetate/methanol/triethylamine to elute the product to afford 24 mg N-butyl-2,3-difluoro-N-[1-(4-piperidin-1-yl-but-2-enyl)-1H-benzoimidazol-2-ylmethyl]-benzamide.
