Procedure

6.76 g (24.38 mmol) of tert-butyl{2-[(6-amino-5-cyanopyridin-2-yl)amino]ethyl}carbamate (Example 8A) were dissolved in 122 ml of a 4 N solution of hydrogen chloride in dioxane and stirred for 30 min. The reaction mixture was concentrated to half of its original volume, and the same amount of diethyl ether was added. The reaction mixture was stirred for 20 min, and the product was filtered off and washed with diethyl ether. This gave 5.43 g (89% of theory) of the product as a solid.
