Procedure
A solution of 4-(2,6-dichloro-pyrimidin-4-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (3.1 g, 8.93 mmol) in ethanol (40 mL) and 4 M HCl in dioxane (70 mL) was stirred at rt for 2 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): 247.3 [M+H]+.
