We describe herein our results on the organocatalytic synthesis and pharmacological properties of 7-chloroquinoline-1,2,3-triazoyl carboxamides. This class of compounds was synthesized in good to excellent yields by the reaction of 4-azido-7-chloroquinoline with a range of β-oxo-amides in the presence of a catalytic amount of pyrrolidine (5 mol%). The obtained compound 3a was screened for anticonvulsant, antinociceptive and anti-inflammatory activities in vivo. The results demonstrated that compound 3a was effective in decreasing the appearance of seizures induced by pilocarpine and pentylenetetrazole. In addition, compound 3a demonstrated antinoceptive and anti-inflammatory properties for combating acute pain. This protocol is an efficient method for the production of new heterocyclic compounds with pharmacological activities.
