✦ Synopsis

The title compound, C 12 H 16 BrNO 2 , was synthesized in 95% yield by condensation of 5-bromo-2-methoxybenzaldehyde and N-tert-butyl-hydroxylamine acetate in the presence of triethylamine as the base and anhydrous magnesium sulfate as the dehydrating agent. The C N bond leads to a plane containing all atoms of the side chain, excluding the three methyl groups; this plane makes a dihedral angle of 14.44 (3) with the ring plane.

In the title compound, C 19 H 28 BrNO 3 , which crystallizes with two molecules in the asymmetric unit, the six-membered cyclohexanone ring exists in a sightly distorted chair conformation. The bromo and methoxyethoxy groups are oriented axially, whereas the phenyl group and tert-butyl adopt equator
