Microwave assisted synthesis of 2-(4-substituted piperazin-1-yl)-1, 8-naphthyridine-3-carbonitrile as a new class of serotonin 5-HT< sub> 3</sub> receptor antagonists
A series of novel 2-(4-substituted piperazin-1-yl)-1,8-naphthyridine-3-carbonitrile 6 were prepared by microwave irradiation and conventional heating. The intermediate, 2-oxo-1,2-dihydro-1,8-naphthyridine-3-carbonitrile 3, was prepared from 2-aminonicotinaldehyde 1 and ethyl cyanoacetate 2 in the pr...
