N-Substituted dihydropyrimidines, 1, 3, and 4, easily afforded N,N'-disubstituted 2,4-diaminopentanes 2 in good yield by the ring opening reaction with sodium borohydride.The reaction with lithium aluminium hydride was also examined.

1-Aryl-3,4,5,6-tetrahydro-2-(1H)pyrimidinones (I) underwent reductive ring opening reaction with lithium aluminum hydride to afford N-aryl-2,4-diaminopentanes (II) in good yields.On the other hand, 3,4,5,6-tetrahydro-3,4,6-trimethyl-1-phenyl-2-(1H)-pyrimi
