Acetic Acid → 6-[1,2,3]Triazolo[4,5-b]pyrazin-1-ylmethyl-quinoline

참여 물질

반응 단계

A solution of 6-(6-bromo-[1,2,3]triazolo[4,5-b]pyrazin-1-ylmethyl)-quinoline (200 mg, 0.586 mmol) in MeOH (10 mL):AcOH (1 mL): EtOAc (1 mL) was degassed 3 times with nitrogen. To this solution was added Pd/C (20 mg). A balloon containing hydrogen was added via syringe and the reaction was allowed to stir for 18 hours at room temperature. The reaction did not complete and more Pd/C was added (20 mg) and stirred for 18 hours at room temperature. The reaction was stopped when LCMS showed a ratio of 1:1 (product:starting material). The reaction was filtered over celite and washed with EtOAc (50 mL). The filtered solution was concentrated and purified by Biotage silica gel column chromatography with EtOAc: Hexanes to give 30 mg of the product 6-[1,2,3]triazolo[4,5-b]pyrazin-1-ylmethyl-quinoline (20% yield).
