The synthesis and reactions of 1 and 3-hetaryl-substituted 5-aminopyrazoles with aldehydes under the Pictet—Spengler reaction conditions have been studied. It has been shown that the possibility of formation and yields of pyrazolo [3,4-c] isoquinoline derivatives essentially depends on the structure and location of the heterocyclic substituent in the pyrazole core.
