Versuchsvorschrift

To a solution of 4-[5-chloro-2-(4-fluorophenyl)pyrazolo[1,5-α]pyridin-3-yl]-N-phenyl-2-pyrimidinamine (80 mg, 0.19 mmol) in tetrahydrofuran (5 mL) was added n-butyllithium (0.43 mL of 1.6M solution in hexane, 0.67 mmol) at −78° C. The resulting dark solution was stirred for 10 minutes, then quenched by the addition of ethyl disulfide (0.08 mL 6.5 mmol). The reaction mixture was allowed to warm to room temperature, then water and ethyl acetate were added. The phases were separated and the ethyl acetate phase was washed with water, dried (magnesium sulfate), filtered and concentrated. The resulting residue was crystallized from acetonitrile to give N-{4-[5-chloro-7-(ethylsulfanyl)-2-(4fluorophenyl)pyrazolo[1,5-α]pyridin-3-yl]-2-pyrimidinyl}-N-phenylamine (20 mg, 22%) as a solid. 1H NMR (CDCl3): δ 8.30 (d, 1H), 8.22 (d, 1H), 7.66 (m, 3H), 7.40 (t, 2H), 7.1–7.24 (m, 4H), 6.75 (d, 1H), 6.52 (d, 1 H), 3.20 (q, 2H), 1.54 (t, 3H); 19F-NMR (CDCl3): δ −112.55; MS m/z 476 (M+1).
