Procedure

The title compound is synthesized according to general procedure GP7 (method 2) starting from 2.0 g (8.17 mmol) 4-chloro-6-methyl-5-(6-amino-pyridin-3-ylethynyl)-pyrimidine and 1.90 g (9.81 mmol) piperidin-4-yl-acetic acid methyl ester using 3.50 mL (20.4 mmoL) DIPEA in 50 mL ACN. The reaction mixture is stirred for 1 h at 80° C. The solvent is removed under reduced pressure. The residue is taken up in DCM/MeOH and filtered over silica. After removal of the solvent and extractive work up 2.9 g (96%) of the desired product is obtained. The product is used without further purification for the next step.
