Ethyl 1-(2-bromo­propano­yl)-4-hydr­oxy-2,6-diphenyl-1,2,5,6-tetra­hydro­pyridine-3-carboxylate


The title compound, C(23)H(24)BrNO(4), crystallizes with two independent mol-ecules per asymmetric unit. The methyl group of the ethoxy-carbonyl unit is disordered over two positions, with occupancies of 0.715 (12) and 0.285 (12) in one of the independent mol-ecules, and 0.529 (11) and 0.471 (11) in the other mol-ecule. In one of the independent mol-ecules, the tetra-hydro-pyridine ring adopts a half-chair conformation, while in the other it is in a distorted envelope conformation. In each independent mol-ecule, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. The two independent mol-ecules are linked via C-H⋯O hydrogen bonds, forming a chain along the c axis.
