Procedure

2-{5-Chloro-2-[10-(2,2,2-trifluoro-acetyl)-10-aza-tricyclo[6.3.2.0*2,7*]trideca-2,4,6-trien-4-ylamino]-pyrimidin-4-ylamino}-N-methyl-benzenesulfonamide (510 mg, 0.878 mmol) was dissolved in methanol (20 mL) and potassium carbonate (727 mg, 5.27 mmol, 6.0 eq) was added. The reaction was stirred at room temperature for 72 hours and then concentrated under reduced pressure. The residue was taken up in water (30 mL) and the product was extracted into EtOAc (3×30 mL). The combined organic layers were dried (sodium sulfate), filtered, and concentrated under reduced pressure. Purification by basic alumina chromatography using a gradient of 0-5% MeOH/CH2Cl2 as the eluting solvent to obtain 2-[2-(10-aza-tricyclo[6.3.2.0*2,7*]trideca-2,4,6-trien-4-ylamino)-5-chloro-pyrimidin-4-ylamino]-N-methyl-benzenesulfonamide as a white foam (300 mg, 70%).
