Conclusions
In hydrogenation in the vapor phase on a skeletal nickel-aluminum catalyst at 210–220°, 1-furyl-3-aminoalkanes undergo “conjugated” hydrogenolysis of the furan series at the 1,5-, 1,5- and 4,5-, as well as 1,5- and 3,4-bonds, forming 2-methyl-, 2-ethyl-, and 2-n-propyl-5-alkylpyrrolidines in yields of 38, 19, and 43%, respectively.
