A new hydrogenation method for the saturation of the pyrrole ring has
been applied in the hydrogenation of methyl 1-methyl-2-pyrroleacetate
in non-acidic medium. Various catalytic metals and solvents have been
screened. High conversion and selectivity were achieved with rhodium a
nd ruthenium catalysts. In palladium catalyzed hydrogenations the sele
ctivity was improved by appropriate solvents.
