Reduction of the anti-Bredt bishydrazone 4,9-dimethyl-2,3,7,8-tetra-azatetracyclo[7.3.1.0.4,1206,10]trideca-1,6-diene with lithiumaluminium hydride–aluminium chloride or by catalytic hydrogenation gives the bishydrazine 1,6-dimethyl-2,3,7,8-tetra-azatetracyclo[7.3.1.0.4,1206,10]tridecane, but reaction with either lithiumaluminiumhydride or aluminium chloride gives dihydropyrazoles by ring cleavage
