PROCESS FOR PRODUCING TRANS-DIBENZOXENOPYRROLE COMPOUND AND INTERMEDIATE THEREFOR

摘要

A process for producing a trans-dibenzoxenopyrrole compound, characterize d by conducting reduction, leaving-group conversion, hydrogenation, and meth ylation in this order. Thus, a trans-dibenzoxenopyrrole compound can be prod uced through a simpler operation than in conventional processes. Also provid ed are: a novel compound obtained as an intermediate in that process; and a process for producing the intermediate.
