We have developed a solidphasesynthesis route to 1,5-substituted pyrazole-4-carboxamides with three diversity points aimed at the discovery of new compounds as potential G-Protein coupled receptor (GPCR) ligands. The new chemistry involves acylation of a resin bound secondary amine with a β-ketoester via transamidation, conversion of the resulting β-ketoamide to the corresponding vinylogous amide
