Procedure
A solution of 4-(3-acetylamino-phenylamino)-piperidine-1-carboxylic acid tert-butyl ester (0.21 g, 0.63 mmol) in 4 M HCl in dioxane (10 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): 234.4 [M+H]+.
