Reaction Steps

A mixture of 3.93 gm (0.025 mole) of 2-quinolinecarboxaldehyde, 2.60 gm (0.025 mole) of ethylcarbazate and 100 ml of methanol is refluxed for 8 hrs. The hot solvent is evaporated in vacuo to give a solid. The crude product is crystallized from ethyl acetate/Skellysolve B to yield 1.19 gm (20%) of the title compound, having a melting point of 163°-165° C.
