Reaction Steps

The mixture of 4-{[3-(2-methanesulfinyl-pyrimidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester (from Example 15 supra) (200 mg, 0.42 mmol) and 3-chlorobenzylamine (238 mg, 1.7 mmol) was heated at 130° C. with stirring for 2 hours. The resulting oil was purified by chromatography (silica gel, 7 g, 200-300 mesh, eluting with dichloromethane:methanol, 50:1 to 30:1) to afford 4-({3-[2-(3-chloro-benzylamino)-pyrimidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino}-methyl)-piperidine-1-carboxylic acid tert-butyl ester. (Yield 200 mg, 86.2%).
