Reaction Steps

6.76 g (24.38 mmol) of tert-butyl {2-[(6-amino-5-cyanopyridin-2-yl)amino]ethyl}carbamate (Example 110A) are dissolved in 122 ml of 4N hydrogen chloride in dioxane and stirred for 30 min. The reaction mixture is concentrated to one half, and an equal portion of diethyl ether is added. The reaction mixture is stirred for 20 min, and the product is filtered off and washed with diethyl ether. 5.43 g (89% of theory) of the product are obtained as a solid.
