METHOD FOR PRODUCING HYDRAZIDE COMPOUND AND 1-SUBSTITUTED-1,2-DIHYDROINDAZOL-3-ONE DERIVATIVE, HYDRAZIDE COMPOUND AND 1-SUBSTITUTED-1,2-DIHYDROINDAZOL-3-ONE DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a new hydrazide compound or a 1-substituted-1,2-dihydroindazol-3-one derivative, and a hydrazide compound and a 1-substituted-1,2-dihydroindazol-3-one derivative.;SOLUTION: The method for producing a 1-substituted-1,2-dihydroindazol-3-one derivative comprises (1) producing a hydrazide compound from a 2-haloaryl acid chloride from hydrazine and (2) subjecting the hydrazide compound to an intramolecular coupling.;COPYRIGHT: (C)2009,JPO&INPIT
