sodium thiosulfite anhydrous → 6-[(5-Fluoro-2-methoxy-pyridin-3-ylmethyl)-amino]-pyridine-3-carbaldehyde

참여 물질

반응 단계

To {6-[(5-fluoro-2-methoxy-pyridin-3-ylmethyl)-amino]-pyridin-3-yl}-methanol (92, 0.353 g, 1.34 mmol) dissolved in 8 mL of tetrahydrofuran, Dess-Maritn periodinane (0.626 g, 1.47 mmol) was added and the reaction stirred at room temperature for 1 hour. The reaction was poured into aqueous saturated sodium thiosulfite and the aqueous layer was extracted with ethyl acetate. The combined organic layer was washed with brine, dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material was purified by silica gel column chromatography eluting with ethyl acetate and hexane. Appropriate fractions were combined and concentrated under vacuum to provide the desired compound. MS (ESI) [M+H+]+=262.3.
