The asymmetric unit of the title compound, C(30)H(34)N(4)O(6), contains two independent mol­ecules. In one independent mol­ecule, the two eth­oxy­carbonyl groups are each disordered over two conformations with occupancy ratios of 0.586 (2):0.414 (2) and 0.508 (2):0.492 (2).

Sumario:The asymmetric unit of the title compound, C(30)H(34)N(4)O(6), contains two independent mol­ecules. In one independent mol­ecule, the two eth­oxy­carbonyl groups are each disordered over two conformations with occupancy ratios of 0.586 (2):0.414 (2) and 0.508 (2):0.492 (2). The crystal packing exhibits weak inter­molecular C—H⋯O hydrogen bonds.
