Abstract

In the title compound, C(22)H(23)N(3)O(4), the tolyl ring is almost perpendicular [83.86 (7)°] to the best plane through the eight atoms of the pyrrolizidine ring system. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond. The crystal packing features inversion dimers with R(2) (2)(8) motifs linked by pairs of N-H⋯O hydrogen bonds.
