Thioglycolic Acid → HCID 408483, compound

Participants

Reaction Steps

4-Chloro-2-phenylquinoline (3 g) and thioglycolic acid (1.38 g) in pyridine (40 cc) are heated under reflux for 4 hours. After evaporation of the pyridine under reduced pressure, the residue is taken up with water (125 cc) and normal aqueous sodium hydroxide solution (40 cc). The aqueous phase is washed with ethyl ether (2×50 cc), acidified to pH 5 with glacial acetic acid and extracted with ethyl ether (3×50 cc). The ether phase is washed with water, dried over magnesium sulphate and evaporated under reduced pressure. [(2-Phenyl-4-quinolyl)thio]acetic acid (3.2 g), m.p. 138° C., is thereby obtained.
