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 (0.015 g, 0.034 mmol) (from Example 46, Step 15) and 2-bromoethanol (0.0097 mL, 0.14 mmol) were combined in N,N-dimethylformamide (1 mL) with triethylamine (0.019 mL, 0.14 mmol) at room temperature. The reaction was heated to 85° C. and after heating for 2 hrs the reaction was concentrated in vacuo and the residue was purified by prep HPLC on a C-18 column eluting water:acetonitrile gradient buffered pH 10 to give the desired compound as a white amorphous solid (0.008 g, 50%). LCMS calculated for C23H28ClN8O2 (M+H)+: m/z=483.2; found: 483.2.
