実験手順

4-(4,6-Dichloro-pyrazolo[3,4-d]pyrimidin-1-yl)-piperidine-1-carboxylic acid tert-butyl ester was prepared using Method C described for the preparation of Intermediate 19, by the reaction of 4-(tert-butoxycarbonyl-hydrazino)-piperidine-1-carboxylic acid tert-butyl ester (Intermediate 15) with 2,4,6-trichloro-pyrimidine-5-carbaldehyde (which can be prepared from barbituric acid using the procedure of J. Dehnert DE 3603797).
