Procedure
A mixture of 2-bromo-N-[1-(2-chloro-6-morpholin-4-yl-9H-purin-8-yl)-ethyl]-acetamide (275 mg, 0.68 mmol) and cesium carbonate (0.48 g, 1.36 mmol) in anhydrous DMF (10 mL) was stirred at RT for 2 h, then diluted with water and extracted five times with ethyl acetate. The combined organic extracts were dried (Na2SO4), filtered and concentrated in vacuo. The resulting residue was subjected to flash chromatography (SiO2) gradient 0-5% methanol in DCM) to give 3-Chloro-8-methyl-1-morpholin-4-yl-7,8-dihydro-2,4,4b,7,9-pentaaza-fluoren-6-one (93 mg, 42%). LCMS RT=2.41 min, [M+H]+=323/325
