To a solution of 4-(5-phenyl-pyrimidin-2-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (1.06 g, 3.00 mmol) in ethanol (10 mL) was added 4 M HCl in dioxane (10 mL) and the reaction mixture 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): 255.6 [M+H]+.
