A series of new N-heterocyclic or phenoxy substituted roflumilast analogues have been designed and synthesised. N-heterocyclic or phenoxy substituted benzaldehydes were first prepared from 3-hydroxy-4-methoxybenzaldehbyde and 1-bromo-3-chloropropane by an alkylation reaction. The roflumilast analogues were then obtained by oxidation, acylation, amidation and alkylation reactions. These compounds were characterised by H-1 NMR, IR, ESI-MS and elemental analyses.
