Reaction Steps

A solution of 4-(pyrimidin-5-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (1.30 g, 4.67 mmol) in 4 M HCl in dioxane (20 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): 179.1 [M+H]+.
