Abstract

Procedure for the preparation of a mercapto-4-pyrazolo [3,4-d] pyrimidine that responds to the general formula: **(See formula)** wherein R1 and R2 are hydrogen or radicals belonging to the group consisting of the alkyl, aryl, aralkyl, cycloalkyl, acyl, arisulfonyl radicals and the heterocyclic radicals, while R3 is hydrogen or a radical belonging to the group consisting of the radicals of alkyl, aryl, aralkyl, cycloalkyl, and heterocyclic radicals, characterized by ensuring, in a first phase, the sulfidation of an amino-3-cyano-4-pyrazole of the general formula **(See formula)** by means of a sulphided product of the general formula R3SH (In the previous formulas, R1, R2 and R3 have the same meaning as previously attributed to them, to form an amino-3-thioamido-4-pyrazole, and, in a second phase, to ensure the cyclization of said amino-3 -thamido-4-pyrazole by means of a cyclizing agent.
