Ethyl 2-(7-oxo-3,5-diphenyl-1,4-diaze-pan-2-yl)acetate
Abstract:
In the title compound, C(21)H(24)N(2)O(3), the diazepane ring adopts a chair conformation. The central diazepane ring forms dihedral angles 67.80 (7) and 72.29 (5)° with the two benzene rings. The eth-oxy-carbonyl group is disordered over two conformations with site-occupancy factors of 0.643 (5) and 0.357 (5). In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
