title: 3-tert-Butyl-4-oxo-3,4-dihydro-phthalazin-1-yl 3,5-dimethyl-benzoate.
abstract: The title compound, C(21)H(22)N(2)O(3), was synthesized by the reaction of tert-butyl-hydrazine with phthalic anhydride and further O-benzoyl-ation of the resulting inter-mediate by 3,5-dimethyl-benzoyl chloride. Inter-molecular C-H⋯O=C inter-actions link the mol-ecules into layers.
