The reaction mixture is stirred for 3 hours at 50° C, cooled, and 10 ml of a 5 N ethanolic ammonia solution are added thereto. The organic solvents are evaporated in vacuo and the residual crude base is chromatographed through a column of basic silica gel with benzene which contains 0.5% of methanol. Pure N-[(1-ethyl-2-pyrrolidinyl)-methyl]-2-methoxy-6-chloronicotinamide is obtained as an oil.
