Reaction Steps

2.24 g (3.4 mmol) of tert-butyl 3-[(5-cyanopyridin-2-yl)amino]piperidine-1-carboxylate (Example 60A) are dissolved in 4.3 ml of a solution of hydrochloric acid in dioxane (4M) and stirred at RT for 3 h. After the reaction is complete, the solvent is completely removed. 1.74 g (90% of theory) of the product are obtained as a solid.
