Abstract

A method of producing a pyrido/_3,4-d_/pyridazine derivative represented by the general formula: **(See formula)** (where R1 is hydrogen or a lower alcohol group of 1 to 4 carbon atoms; R2 is an alcohol group of 1 to 4 atoms, an aralkohyl group of 7 to 8 carbon atoms or a phenyl, naphthyl, furyl or pyridyl group, substituted or unsubstituted, the substituent being a lower alkoxy group of 1 to 3 carbon atoms, a lower alcohol group of 1 to 3 atoms, halogen or nitro; R3 is hydrogen or a lower alkoxy group of 1 to 4 carbon atoms and R4 is a substituted or unsubstituted morpholino, piperidino or pyrrolidino group, the substituent being methyl or ethyl) or one of its pharmaceutically acceptable salts that comprises oxidizing a compound represented by the general formula: **(See formula)** wherein each of R2, R3 and R4 have the same meaning as defined above; and R5 is an easily separable hydrocarbon residue.
