Reaction Steps

2-({2-[(4-{[3-chloro-4-(pyridin-2-ylmethoxy)phenyl]amino}-1H-pyrazolo[3,4-d]pyrimidin-3-yl)oxy]ethyl}amino)ethanol (prepared as described in Example 36/30 mg, 0.07 mmol) was dissolved in DMA and the mixture was cooled to −15° C. Acetic anhydride (6 μL, 0.07 mmol) was added and the mixture was stirred for 1 hour. Water was then added and the precipitated solid was filtered and dried to give the title compound (22 mg, 67%); NMR Spectrum (mixture of rotamers): (major isomer) 2.08 (s, 3H), 3.49 (t, 2H), 3.56-3.59 (m, 2H), 3.80 (t, 2H), 4.40 (t, 2H), 4.90 (t, 1H), 5.28 (s, 2H), 7.26 (d, 1H), 7.37 (t, 1H), 7.58 (d, 1H), 7.84-7.98 (m, 2H), 8.16 (d, 1H), 8.28 (s, 1H), 8.30 (s, 1H), 8.59 (d, 1H); Mass Spectrum: 498 (MH+).
