Reaction Steps

Tert-butyl 3-[9-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-7-chloro-6-cyano-2,3-dihydro-1,4-benzoxazepin-4(5H)-yl]azetidine-1-carboxylate (0.015 g, 0.0278 mmol) was dissolved in 4.0 M hydrogen chloride in dioxane (3.0 mL, 12 mmol) at room temperature and stirred for 1 hr and then concentrated in vacuo to give 9-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-4-azetidin-3-yl-7-chloro-2,3,4,5-tetrahydro-1,4-benzoxazepine-6-carbonitrile trishydrochloride as a semi-solid. LCMS calculated for C21H24ClN8O (M+H)+: m/z=439.1; found: 439.1.
