Procedure
To a solution of 5 ml of 5% trifluoroacetic acid in dichloromethane 0.8 g (1.67 mmol) of {5-[2-(4-benzyl-piperidin-1-yl)-2-oxo-acetylamino]-1H-benzimidazol-2-yl}-carbamic acid tert-butyl ester is added. The reaction mixture is stirred for 48 hours at 20° C. The precipitated crystals are filtered off and washed with dichloromethane to yield 0.8 g (97.1%) of the title compound. Melting Point: 121° C.
Workup
- filtrationThe precipitated crystals are filtered off
