Crystal structure of the meso compound (2R,6S)-4-(5-bromo-pyrimidin-2-yl)-2,6-di-methyl-morpholine.

The title compound, C10H14N3OBr, was prepared by a nucleophilic aromatic substitution reaction between 2,6-di-methyl-morpholine and 2-chloro-pyrimidine, followed by bromination of the pyrimidine ring. The compound crystallizes in the monoclinic system (space group P21/c) with four mol-ecules in the unit cell (Z = 4). The mol-ecule exhibits approximate C S point-group symmetry (r.m.s. deviation: 0.1072 Å). The arrangement of the mol-ecules in the solid state is dominated by close packing. C-H⋯N contacts between pyrimidinyl rings in adjacent mol-ecules with an R 2 2(6) motif are encountered, whereas the bromine atom does not exhibit any short contacts that could be regarded as halogen bonds.
