Procedure
To a cooled (0° C.) solution of tert-butyl 2-(piperidin-1-ylmethyl)-6,7-dihydrothiazolo[5,4-c]pyridine-5(4H)-carboxylate (0.534 mmol) in dichloromethane (3 ml) was added trifluoroacetic acid (1 ml) and reaction mixture was stirred at room temperature for 2 h. Solvent was evaporated under reduced pressure and residue was azeotroped twice with dichloromethane and used in the next step.
