Procedure

To a solution of [1-(3-methyl-[1,2,4]thiadiazol-5-yl)-piperidin-4-yl]-carbamic acid tert-butyl ester (256 mg, 0.86 mmol) in CH2Cl2 (8.6 mL) was added at room temperature under stirring a 2 M HCl solution in diethyl ether (4.3 mL) and was stirred at room temperature over night. The solvent was removed under reduced pressure. The crude product was treated twice with diethyl ether to yield the title compound as a yellow semi-solid (260 mg, 100%)
