Versuchsvorschrift

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 (30 mg, 0.0619 mmol) was placed in acetone (3 mL) and cesium carbonate (60.4 mg, 0.186 mmol, 3.0 eq) was added followed by propargyl bromide (80% in toluene) (7.28 μL, 0.0681 mmol, 1.1 eq). The reaction was stirred at room temperature for 24 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 silica gel chromatography using a gradient of 0-10% MeOH/CH2Cl2 as the eluting solvent. Further purification by prep-HPLC using a gradient of 10-90% acetonitrile/water to obtain 2-[5-chloro-2-(10-prop-2-ynyl-10-aza-tricyclo[6.3.2.0*2,7*]trideca-2,4,6-trien-4-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzenesulfonamide as a thin yellow film (6.9 mg, 21%). LCMS (m/e) 523 (M+1); 1H-NMR (CDCl3, 400 MHz) δ 9.10 (s, 1H), 8.49 (d, 1H, J=8.0 Hz), 8.09 (s, 1H), 7.95 (dd, 1H, J=1.6 and 8.0 Hz), 7.60-7.53 (m, 1H), 7.30-7.20 (m, 3H), 7.01 (d, 1H, J=7.9 Hz), 6.99 (bs, 1H), 4.76-4.67 (m, 1H), 3.36 (d, 2H, J=2.4 Hz), 3.05-3.00 (m, 1H), 2.95-2.84 (m, 3H), 2.63 (d, 3H, J=5.3 Hz), 2.51-2.43 (m, 2H), 2.21-2.15 (m, 2H), 2.14 (t, 1H, J=2.3 Hz), 1.70-1.60 (m, 2H).
