実験手順

The title compound is synthesized according to general procedure GP7 starting from 2.0 g (7.7 mmol) 4-chloro-6-methyl-5-(6-amino-pyridin-3-ylethynyl)-pyrimidin-2-ylamine and 1.33 g (8.47 mmol) piperidine-4-carboxylic acid ethyl ester using 1.18 mL (8.5 mmol) triethylamine in 12 mL NMP. Work up is performed by addition of 50 mL water to the reaction mixture and stirring for 30 min. The solid material is filtered off, washed with water (50 mL three times) yielding 1.58 g (4.15 mmol) of the desired product with sufficient purity.
