2-{[4-({3-methyl-4-[(6-methylpyridin-3-yl)oxy]phenyl}amino)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]oxy}ethanol (prepared as described in Example 8/1.7 g, 4.33 mmol) was dissolved in thionyl chloride (10 ml) and DMF (100 μL) was added. The mixture was refluxed for 2 hours and then the volatiles were removed under reduced pressure. The residue was triturated with a saturated solution of sodium bicarbonate and the solid filtered and washed with ether to provide the title compound (1.5 g, 84%); NMR Spectrum: 2.20 (s, 3H), 2.44 (s, 3H), 4.09 (t, 2H), 4.60 (t, 2H), 6.96 (d, 1H), 7.18-7.25 (m, 2H), 7.60 (d, 1H), 7.67 (s, 1H), 8.17 (s, 1H), 8.31 (s, 1H), 8.34 (br s, 1H); Mass Spectrum: 411 (MH+).
