Reaction Steps
IN Aqueous sodium hydroxide solution (60 ml) was added dropwise to a mixed solution of ethyl 7-chloro-2-oxo -1,2,3,4-tetrahydro-3-quinolinecarboxylate (14.39 g) in THF (180 ml) and methanol (120 ml) at 0° C. The reaction mixture was stirred at room temperature for 24 hours. 1N Hydrochloric acid (70 ml) was added dropwise to the reaction mixture at 0° C., which was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous sodium chloride solution, then dried and concentrated. The obtained crude crystals were washed with IPE to obtain the entitled compound (12.15 g).
