There is provided a method for producing aminobenzopyran compound, which
results in little wastes, has no influence on reactors and necessitates a
simple work-up procedure. Concretely, it is a method for producing
aminobenzopyran compound of formula (2) ##STR00001## characterized by
reducing a nitro group on 2,2-dimethyl 2H-1-benzopyran compound of
formula (1) ##STR00002## with hydrazine in the presence of a metal
catalyst.
