A URAT1 activity inhibitor containing a nitrogen-containing fused ring compound represented by the following formula [1]:
wherein each symbol is as defined in the description. The present invention is useful for the prophylaxis or treatment of pathology showing involvement of uric acid, such as hyperuricemia, gouty tophus, acute gouty arthritis, chronic gouty arthritis, gouty kidney, urolithiasis, renal function disorder, coronary artery disease, ischemic heart disease and the like.
The potential utility of polymethylhydrosiloxane (PMHS) as a reducingagent for reductive N-alkylation of aromatic amines and nitrocompoundsusing nitriles as an alkylating agent and Pd(OH)2/C as a catalyst is described. The application of this method for the synthesis of several heterocyclic compounds is also reported.
