2-Bromoethanol (4.7 μL, 0.066 mmol) was added to a mixture of 9-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-7-chloro-2,3,4,5-tetrahydro-1,4-benzoxazepine-6-carbonitrile bishydrochloride (15 mg, 0.039 mmol) (from Example 46, step 13) and triethylamine (10 μL, 0.09 mmol) in N,N-dimethylformamide (2 mL). The reaction was heated at 80° C. for 3 h and then allowed to cool. The product was purified without workup by prep HPLC on a C-18 column eluting water:acetonitrile gradient buffered pH 10 to give the desired compound as white amorphous solid (0.08 g, 50%). LCMS calculated for C20H23ClN7O2 (M+H)+: m/z=428.1; found: 428.2.
