실험 절차

To a cold (0° C.) solution of N-[3-[2-(cyclopentylamino)pyrimidin-4-yl]-2-(4-methoxyphenyl)pyrazolo[1,5-a]pyridin-7-yl]butane-1,4-diamine (21 mg, 0.04 mmol) in dichloromethane (3 mL) was added triethylamine (0.02 mL, 0.13 mmol) and methanesulfonyl chloride (0.05 mL). The resultant solution was stirred at 0° C. for 1 hour and saturated aqueous sodium bicarbonate was added. The organic layer was washed with brine. The aqueous layer was extracted with dichloromethane and the combined organics were dried over sodium sulfate. Filtration and concentration followed by flash chromatography (5% methanol in dichloromethane) provided N-(4-{[3-[2-(Cyclopentylamino)pyrimidin-4-yl]-2-(4-methoxyphenyl)pyrazolo[1,5-a]pyridin-7-yl]amino}butyl)methanesulfonamide (25 mg, 99%) a yellow solid. 1H NMR (CDCl3): δ 8.01 (d, 1 H), 7.79 (d, 1 H), 7.59 (d, 2 H), 7.32 (m, 1 H), 7.01 (d, 2 H), 6.34 (d, 1 H), 6.13 (m, 1 H), 6.00 (d, 1 H), 5.34 (d, 1 H), 5.02 (m, 1 H), 4.38 (m, 1 H), 3.90 (s, 3 H), 3.38 (m, 2 H), 3.13 (m, 2 H), 2.94 (s, 3 H), 2.14–2.06 (m, 2 H), 1.82–1.54 (m, 10 H); MS m/z 550 (M+1).
