380 mg (0.85 mmol) of tert-butyl 3-({6-[(tert-butoxycarbonyl)amino]-5-propanoylpyridin-2-yl}amino)piperidine-1-carboxylate (Example 26A) were dissolved in 10 ml of a solution of hydrochloric acid in dioxane (4 M), and the mixture was stirred at RT for 20 h. After the reaction had gone to completion, the reaction mixture was diluted with diethyl ether (100 ml), and the recipitate was filtered off and washed with diethyl ether (100 ml) and dried. This gave 170 mg (70% of theory) of the product as a solid.
