4-(6-Acetylamino-2-chloro-pyrimidin-4-ylamino)-piperidine-1-carboxylic acid tert-butyl ester → N-[2-Chloro-6-(piperidin-4-ylamino)-pyrimidin-4-yl]-acetamide dihydrochloride

Participants

Reaction Steps

A solution of 4-(6-acetylamino-2-chloro-pyrimidin-4-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (0.1 g, 0.27 mmol) in ethanol (2 mL) and 4 M HCl in dioxane (2 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): 270.0 [M+H]+.
