Procedure

To [1-(1H-pyrazolo[3,4-d]pyrimidin-4-yl)-piperidin-4-yl]-carbamic acid tert-butyl ester (28 mg, 0.088 mmol) was added HCl (1 ml, 4M solution in dioxane, 4 mmol). The suspension was stirred at room temperature for 1 hour, and then diluted with diethyl ether (4 ml). The ethereal layer was discarded and the solid washed with a further portion of diethyl ether (2 ml). The ethereal layer was again discarded, and the resultant solid dried under high vacuum to yield the desired product (34 mg). The free base was liberated by dissolution of this material in methanol, loading onto an acidic resin SCX-2 cartridge, and elution from the cartridge with ammonia in methanol. LC/MS Rt 0.86 [M+H]+ 219
