tert-Butyl (3S)-9-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-7-chloro-6-fluoro-3-methyl-2,3-dihydro-1,4-benzoxazepine-4(5H)-carboxylate (13 mg, 0.026 mmol) was stirred in methylene chloride (100 μL, 2 mmol) with N,N-diisopropylethylamine (14 μL, 0.079 mmol) and cooled to 0° C. Methanesulfonyl chloride (2.6 μL, 0.034 mmol) was added, and the mixture was stirred at 0° C. for 1 hr. The mixture was evaporated and diluted with methanol. The reactions were purified by prep HPLC on C-18 column eluting water:acetonitrile gradient buffered pH 10 to give two enantiomers: Peak #1 (Example 35): LCMS calculated for C19H23ClFN6O3S (M+H)+: m/z=469.1; found: 469.1; Peak #2 (Example 36): LCMS calculated for C19H23ClFN6O3S (M+H)+: m/z=469.1; found: 469.1.
