HCID 11053048, compound → 3-(Quinolin-3-yl)propanoic acid

Participants

Reaction Steps

A solution of 3-quinolinepropanoic acid methyl ester (2.21 g, 10.3 mmol) in 10% KOH/MeOH (48.2 mL), H2O (20 mL) and methanol (134 mL) was stirred at room temperature for 3 h. Upon completion of reaction, the solution was concentrated and the aqueous residue was acidified to pH 5-6 with glacial HOAc. A crystalline solid formed which was filtered, washing with H2O until the filtrate was neutral and dried to give 3-quinolinepropanoic acid (1.84 g, 9.14 mmol) in 89% yield as a solid, mp 180°-181° C.
