In the GABA 250MG title compound, C29H24N2O2, the hydrofuran ring is twisted with puckering parameters Q = 0.1553 (16) Å and ϕ = 305.0 (6)°.
In the crystal, the graph-set motifs of the interaction pattern are an R22(16) motif involving dimers through N—H.N hydrogen bonds across centres of inversion and a Egg Chalk C(6) motif through C—H.O hydrogen-bond between glide-related molecules.
Together, these generate [101] ladder-like chains.
