Reaction Steps

Lithium aluminum hydride (1.08 g, 27.7 mmol) was added to a stirred solution of 3-(dipropylamino)-3,4-dihydro-8-methoxy-2(1H)quinolinone (1.05 g, 3.8 mmol) in THF (50 mL) and the solution was heated at 50° C. for 1 hour. After cooling, ethyl acetate followed by methanol were added to destroy excess hydride, and the solvent was evaporated. The residue was partitioned between ethyl acetate and water. Evaporation of the ethyl acetate gave 0.98 g of 1,2,3,4-tetrahydro-8-methoxy-N,N-dipropyl-3-quinolinamine as an oil.
