The crystal structure of the title benzofuran derivative, C~16~H~23~NO~3~, has been elucidated. The tricyclic core, __i.e.__ the tetrahydrobenzo–dihydrofuro–pyrrolidine ring system, is non-planar owing to the folding of the five-membered rings at their __cis__ junction. The cyclohexene ring assumes
