実験手順

A solution of 4-(2,5,6-trichloro-pyrimidin-4-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (0.85 g, 2.23 mmol) in 4 M HCl in dioxane (100 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): 283.4 [M+H]+.
