実験手順

4.0 g (15.25 mmol) of tert-butyl {2-[(5-cyanopyridin-2-yl)amino]ethyl}carbamate (Example 12A) are dissolved in 150 ml of dichloromethane, and 17.39 g (152.5 mmol) of trifluoroacetic acid are slowly injected. The mixture is stirred at RT for 16 h and then all volatile constituents are removed in vacuo. 4.3 g (91% of theory) of the product are obtained as a resin.
