Versuchsvorschrift

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 (0.1 mL), and diethyl chlorophosphate (0.1 mL of a stock solution prepared from 0.1 mL of diethyl chlorophosphate in 3 mL of dichloromethane). The resultant solution was stirred for 3 hours at 0° C. and then quenched by the addition of saturated aqueous sodium bicarbonate. 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 diethyl 4-{[3-[2-(cyclopentylamino)pyrimidin-4-yl]-2-(4-methoxyphenyl)pyrazolo[1,5-a]pyridin-7-yl]amino}butylamidophosphate (22 mg, 81%) as a yellow solid. 1H NMR (CDCl3): δ 7.98 (d, 1 H), 7.76 (d, 1 H), 7.55 (d, 2 H), 7.28 (m, 1 H), 6.96 (d, 2 H), 6.31 (d, 1 H), 6.06 (m, 1 H), 5.97 (d, 1 H), 5.11 (d, 1 H), 4.34 (m, 1 H), 4.09–3.98 (m, 4 H), 3.86 (s, 3 H), 3.37 (m, 2 H), 2.95 (m, 2 H), 2.64 (m, 1 H), 2.11–1.48 (m, 12 H), 1.31–1.27 (m, 6 H); MS m/z 608 (M+1).
