Reaction Steps

2-Chloro-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-benzo[d]imidazole (0.5 g) was placed in a flask with azetidine (0.48 mL), Hunig's base (iPr2Net, 1.5 mL) in 1 mL of ethanol. The reaction was heated to 50° C. overnight and then concentrated to dryness to get 0.55 g of crude 2-(azetidin-1-yl)-1-(2-(trimethylsilyl)ethoxy)methyl)-1H-benzo[d]imidazole.
