Procedure
A reaction mixture of tert-butyl 4-(4-bromo-1-(2-((methylsulfonyl)oxy)ethyl)-1H-imidazol-2-yl)piperidine-1-carboxylate (28.0 g) and azetidine (11 ml) in to DMF (200 ml) was stirred at 50° C. overnight. The reaction was diluted with EA, washed with water followed by saturated aqueous sodium chloride, dried and concentrated. The residue was purified by column chromatography to give tert-butyl 4-(1-(2-(azetidin-1-yl)ethyl)-4-bromo-1H-imidazol-2-yl)piperidine-1-carboxylate as off-white solid. (17.2 g).
