Participants

Reaction Steps

Trifluoroacetic acid (1 ml) was added at 0° C. to a solution of tert-butyl methyl(1-(1-methyl-1H-imidazol-2-yl)piperidin-4-yl)carbamate (241 mg, 0.82 mmol, 1 eq) in dichloromethane (5 ml), and the reaction mixture was stirred for 1 h at room temperature. Concentration under reduced pressure was then carried out. The crude product so obtained was used in the next stage without being purified further.
