Versuchsvorschrift

Tert-butyl 7-(6-(4-(3-pyridin-4-ylureido)phenyl)-1-(2,2,2-trifluoroethyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-9-oxa-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate.hydrochloride (256 mg, 0.38 mmol) was dissolved in dichloromethane (20 mL) with the aid of a minimum volume of methanol. The solution was treated with 4 N hydrogen chloride in dioxane (2 mL), which caused the precipitation of a white solid within 10 minutes. The solid was collected by Buchner filtration, washed with methanol, and dried under house vacuum. A portion of the crude solid (assumed dihydrochloride) was purified by reverse-phase high performance liquid chromatography using a Phenomenex Prodigy 21 mm×250 mm column, running a gradient elution of 5% acetonitrile/95% of 0.1% aqueous trifluoroacetic acid to 65% acetonitrile to provide 1-{4-[4-(9-oxa-3,7-diazabicyclo[3.3.1]non-3-yl)-1-(2,2,2-trifluoroethyl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl]phenyl}-3-pyridin-4-ylurea.2TFA (22 mg). MS (ES+): 540.2 (M+H)+
