Procedure

A solution of 4-(5-trifluoromethyl-pyridin-2-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (0.69 g, 2.00 mmol) in ethanol (40 mL) and 4 M HCl in dioxane (40 mL) was stirred at rt for 1 h. The solvent was removed under reduced pressure and the crude product used in the consecutive step without further purification assuming quantitative deprotection and formation of the dihydrochloride salt. MS (ISP): 246.1 [M+H]+.
