Procedure

1,5-Dimethyl-6-oxo-1,6-dihydro-pyridine-3-carboxylic acid D1 (3.589 g; 21.47 mmol) and (5-amino-4-benzylamino-pyridin-2-yl)-carbamic acid tert-butyl ester E-2.11 (4.500 g; 14.31 mmol) are dissolved in THF and and cooled to 0° C. DIPEA (5.539 g; 42.94 mmol) and HATU (10.878 g; 28.63 mmol) are added. The mixture is stirred at room temperature for 1 hr. Water is then added to the reaction mixture, precipitation of the product occurs. The precipitate is filtered off and dried under vacuum. The residue is used in the next step without further purification.
