In the title compound, C 32 H 25 NO 5 , the furan and pyrrole rings each adopt an envelope conformation, the respective flap atoms being the C atom bearing the pyrene substituent and the CH 2  atom adjacent to the N atom. The mol­ecular conformation is stabilized by an intra­molecular O—H⋯N hydrogen bond. In the crystal, C—H⋯O contacts link the mol­ecules, forming a two-dimensional network parallel to (001).
