실험 절차

To a solution of 2-(4-Bromophenyl)-N-butyl-3-[2-(butylamino)-4-pyrimidinyl]pyrazolo-[1,5-a]pyridin-7-amine (52 mg, 0.11 mmol) in tetrahydrofuran was added phenylboronic acid (26 mg, 0.21 mmol), sodium carbonate (0.21 mL, 2 M aqueous, 0.42 mmol), and dichlorobistriphenylphosphine palladium (II) (7.5 mg, 0.01 mmol). The mixture was heated at reflux for 3.5 hours. The resultant solution was cooled to room temperature and diluted with ether and water was added. The organic layer was washed with brine. The aqueous layer was extracted with ether and the combined organics dried over magnesium sulfate. Filtration and concentration followed by flash chromatography provided 2-[1,1′-biphenyl]-4-yl-N-butyl-3-[2-(butylamino)-4-pyrimidinyl]pyrazolo[1,5-a]pyridin-7-amine (37 mg, 73%) as a yellow solid. 1H NMR (CDCl3): δ 8.05 (d, 1 H), 7.83–7.69 (m, 7 H), 7.51 (m, 2 H), 7.43–7.33 (m, 2 H), 6.44 (d, 1 H), 6.12 (t, 1 H), 6.05 (d, 1 H), 5.16 (broad, 1 H), 3.52 (m, 2 H), 3.42 (m, 2 H), 1.84–1.43 (m, 8 H), 1.05–0.99 (m, 6 H); MS m/z 491 (M+1).
