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 (33 mg, 0.07 mmol) in N,N-dimethylformamide (3 mL) was added triethylamine (0.03 mL, 0.21 mmol) and d-biotin-N-hydroxysuccinimide ester (27 mg, 0.08 mmol). The resultant mixture was warmed to room temperature and stirred for 30 minutes. A subsequent 5 mg of d-biotin-N-hydroxysuccinimide ester was added and the mixture was stirred an additional 30 minutes. Water was added and the layers were separated. The organic layer was washed with saturated aqueous sodium bicarbonate and then 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% to 8% methanol in dichloromethane) provided 5-[(3aS,4S,6aR)-2-oxohexahydro-1H-thieno[3,4-d]imidazol-4-yl]-N-(4-{[3-[2-(cyclopentylamino)-pyrimidin-4-yl]-2-(4-methoxyphenyl)pyrazolo[1,5-a]pyridin-7-yl]amino}butyl)-pentanamide (25 mg, 51%) as a yellow solid. 1H NMR (CDCl3): δ 7.98 (d, 1 H), 7.80 (d, 1 H), 7.58 (d, 2 H), 7.32 (m, 1 H), 7.00 (d, 2 H), 6.60 (s,1 H), 6.39 (m, 1 H), 6.33 (d, 1 H), 6.18 (m, 1 H), 6.02 (m, 1 H), 5.72 (s, 1 H), 5.62 (broad, 1 H), 4.44–4.31 (m, 2 H), 4.19 (m, 1 H), 3.89 (s, 3 H), 3.39 (m, 2 H), 3.28 (m, 2 H), 3.06 (m, 1 H), 2.95 (m, 2 H), 2.77 (dd, 1 H), 2.58 (d, 1 H), 2.20–2.05 (m, 4 H), 1.82–1.54 (m, 12 H), 1.39 (m, 2 H); MS m/z 698 (M+1).
