Trifluoroacetic acid (2 ml) was added at 0° C. to a solution of tert-butyl methyl(1-(6-methylpyrazin-2-yl)piperidin-4-yl)carbamate (250 mg, 0.816 mmol, 1 eq) in dichloromethane (10 ml) and the reaction mixture was stirred for 2 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.
