Procedure

2-[(4-{[3-methoxy-4-(pyridin-2-ylmethoxy)phenyl]amino}-1H-pyrazolo[3,4-d]pyrimidin-3-yl)oxy]ethanol (prepared as described in Example 7/500 mg, 1.22 mmol) was dissolved in dry pyridine (12 ml) and methanesulfonyl chloride (142 μl, 1.84 mmol) was added drop-wise under argon. The mixture was stirred for 1 hour at room temperature then partitioned between water and methylene chloride. The organic layer was washed with water, dried over MgSO4 and evaporated under vacuum. The residue was triturated in ether, filtered and dried to give the title compound as a tan solid (462 mg, 78%); NMR Spectrum: 3.28 (s, 3H), 3.80 (s, 3H), 4.58 (d, 2H), 4.69 (d, 2H), 5.16 (s, 2H), 7.03 (d, 2H), 7.37 (m, 3H), 7.55 (d, 1H), 7.85 (td, 1H), 8.13 (s, 1H), 8.29 (s, 1H), 8.58 (d, 1H).
