Reaction Steps

1N Aqueous sodium hydroxide solution (30 ml) was added dropwise to a mixed solution of ethyl 6-chloro-2-oxo-1,2,3,4-tetrahydro-3-quinolinecarboxylate (7.278 g) in THF (90 ml) and methanol (60 ml) at 0° C. The reaction mixture was stirred at room temperature for 18 hours. 1N Hydrochloric acid (30 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 diethyl ether to obtain the entitled compound (6.06 g).
