Bromination of 1-methylpiperidine-4-carboxaldehyde gave 4-bromo-1-methylpiperidine-4-carboxaldehyde hydrobromide which was used to synthesize 1,4,9-triazaspiro<5,5>undecane and 3,7,11-triazaspiro<5,6>dodecane.Cyanoethylation and alkylation with various alkyl halides gave their mono- and di-substituted derivatives.The side chain nitrile group was reduced and the hydrazide was obtained from the ester analog.
