Reduction of 1-methyl-3-cyano-pyridinium iodide with excess sodium borohydride has been found to give l-methyl-3-cyano-l,2,5,6-tetrahydro-pyridine (I) and l-methyl-3-cyano-l,6-dihydro-pyridine (II a) in approximately equal yields.The constitution of IIa was deduced by comparison with l-methyl-3-cyano-1,4-dihydro-pyridine (II b), obtained exclusively on treatment of 1-methyl-3-cyano-pyridinium iodide
