Hydrogen chloride-ethyl acetate → HCID 67539033, compound

Participants

Reaction Steps

To 2.0 mL of ethyl acetate solution containing 25 mg of N-methyl-2-oxo-1-(2-(4-(((5-(2-thienyl)isooxazol-3-yl)methyl)amino)piperidin-1-yl)ethyl)-1,2-dihydroquinoline-4-carboxamide, 0.5 mL of 4.0 mol/L hydrogen chloride/ethyl acetate solution was added under ice-cooling. The mixture was stirred at the same temperature for 10 min, and the solvent was removed under reduced pressure. To the residue thus obtained, ethyl acetate was added, the resulting solid was filtered to give 23 mg of N-methyl-2-oxo-1-(2-(4-(((5-(2-thienyl)isooxazol-3-yl)methyl)amino)piperidin-1-yl)ethyl)-1,2-dihydroquinoline-4-carboxamide hydrochloride as a light brown solid.
