Versuchsvorschrift

To a solution of 3,5-dichloro-4-[7-fluoro-4-(6-methylpyrimidin-4-ylamino)pyrazolo[4,3-c]pyridin-2-yl]benzaldehyde (125 mg, 0.3 mmol) in ethanol (IMS grade, 5 mL) and THF (2 mL) was added sodium borohydride (14 mg, 0.36 mmol) and the reaction mixture was stirred at room temperature for 2 hours. The resultant mixture was partitioned between ethyl acetate and water and the layers were separated. The organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel flash chromatography (0-1% methanol in ethyl acetate) to yield a solid, to which was added HCl (1.25 N in propan-2-ol, 10 mL) and the mixture was stirred at room temperature for 1 hour. The solid obtained was collected by filtration and dried to afford the title compound as an off-white solid (62 mg, 45% yield). 1H NMR (400 MHz, DMSO-d6): δ 9.35 (br s, 1H), 8.97 (s, 1H), 8.36 (br s, 1H), 8.10 (d, J=3.5 Hz, 1H), 7.75 (s, 2H), 4.68 (s, 2H), 2.57 (s, 3H). LCMS (Method B): RT=2.89 min, m/z: 419 [M+H+].
