Participants

Reaction Steps

A solution of 4-(4-methyl-quinolin-2-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (0.54 g, 1.58 mmol) in 4 M HCl in dioxane (50 mL) was stirred at rt for 1 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.
