Novel synthetic routes have been devised for the preparation of previously inaccessible 2,3,7-trisubstituted pyrazolo[1,5-d][1,2,4]triazines 2. These compounds are high affinity ligands for the GABA(A) benzodiazepine binding site and some analogues show functional selectivity for agonism at alpha 3-containing receptors over alpha 1-containing receptors with the lead compound being 32.

A class of substituted pyrazolo[1,5-d][1,2,4]triazine derivatives, possessing an optionally substituted cycloalkyl, phenyl or heteroaryl substituent at the 7-position and a substituted alkoxy moiety at the 2-position, are selective ligands for GABAA receptors, in particular having high affinity for the α2 and/or α3 subunit thereof, and are accordingly of benefit in the treatment and/or prevention of disorders of the central nervous system, including anxiety and convulsions.
