Abstract

A procedure for the preparation of coumarin derivatives of formula (I): **(See formula)** or a pharmaceutically acceptable salt thereof, where R is an alkyl or aryl group; R1, R2, R3, and R4 are the same or different and each is hydrogen or an alkyl, alkoxy, aryl, aralkyl, heterocyclic, halogen or carboxylic acid group or a pharmaceutically acceptable salt, ester or amide derived from an acidic group. carboxylic, or an acyloxy group or any two of the radicals R1, R2, R3 and R4 taken together represent the remainder of a substituted or unsubstituted carbocyclic or heterocyclic group; with the proviso that when R1 = R2 = R3 = R4 = H, then R is not methyl; whose procedure is to react a compound of formula: **(See formula)** with ammonium azide.
