In the mol-ecule of the title compund [systematic name: N-butyl-N-ethyl-2,5,6-trimethyl-7-(2,4,6-trimethyl-phen-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine], C(24)H(34)N(4), the pyrrolopy-rimidine ring system is nearly planar, its five- and six-membered rings forming a dihedral angle of 5.3 (2)°. The benzene ring is nearly orthogonal to the central ring system. The N atom carrying the ethyl and n-butyl groups is flattened pyramidal.
在标题化合物[系统名称：N-丁基-N-乙基-2,5,6-三甲基-7-(2,4,6-三甲基苯基)-7H-吡咯并[2,3-d]嘧啶-4-胺]的分子中，C₂₄H₃₄N₄，吡咯并嘧啶环系几乎是平面的，其五元环和六元环形成5.3 (2)°的二面角。苯环与中心环系几乎正交。携带乙基和正丁基的N原子呈扁平金字塔形。
