実験手順

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-benzamide (30 mg, 0.0667 mmol) was placed in dimethylformamide (3 mL) and cesium carbonate (65 mg, 0.200 mmol, 3.0 eq) was added followed by 2-bromoethyl methyl ether (11.2 mg, 0.0804 mmol, 7.6 μL, 1.2 eq). The reaction was stirred at room temperature for 72 hours and was then concentrated under reduced pressure. The residue was taken up in CH2Cl2 (10 mL) and washed with water (10 mL). The organic layer was dried (sodium sulfate), filtered, and concentrated under reduced pressure. Purification by basic alumina chromatography using a gradient of 0-10% MeOH/CH2Cl2 as the eluting solvent to obtain 2-{5-chloro-2-[10-(2-methoxy-ethyl)-10-aza-tricyclo[6.3.2.0*2,7*]trideca-2,4,6-trien-4-ylamino]-pyrimidin-4-ylamino}-N-methyl-benzamide as a yellow foam (8.25 mg, 24%).
