POTENTIAL ANALGESICS. PART I. SYNTHESIS OF SUBSTITUTED 4-QUINAZOLONES

Using the concept of quarternary carbon and tertiary nitrogen in 13-relationship So each other in a molecule, as an optimal and perhaps an essential feature of potent analgesics, seventeen substituted 4-quinazolones have been synthesised as intermediates in the preparation of substituted 4-quiaszolinuis and their esters for testing their analgesic activity.
