Procedure

tert-Butyl 10-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-8-chloro-7-fluoro-3,4-dihydro-2H-1,5-benzoxazocine-5(6H)-carboxylate (8 mg, 0.02 mmol) was stirred in methylene chloride (80 μL, 1 mmol) with N,N-diisopropylethylamine (8.5 μL, 0.049 mmol) and cooled to 0° C. Methanesulfonyl chloride (1.6 μL, 0.021 mmol) was added and the mixture was stirred at 0° C. for 1 hr. The mixture was evaporated and diluted with methanol and purified by preparative LCMS (pH 10) to give Example 45. LCMS calculated for C19H23ClFN6O3S (M+H)+: m/z=469.1; found: 469.1. 1H NMR (300 MHz, CD3OD): δ 8.14 (s, 1 H), 7.65 (m, 1 H), 6.36 (m, 1 H), 4.58 (m, 2 H), 4.21 (m, 2 H), 3.52 (m, 2 H), 2.87 (s, 3 H), 2.60 (s, 3 H), 1.91 (m, 2 H), 1.80 (m, 3 H).
