✦ Synopsis

Through mono-ester formation of 1,1%-bi-2-naphthol (BINOL) with pivaloyl chloride the selective mono-bromination was achieved cleanly on the other ring to afford 6-mono-bromo-1,1%-bi-2-naphthol in an efficient 86% yield.

In the title compound, C~18~H~29~BrN~4~, both piperazine rings assume a chair conformation. Weak intermolecular C—H...Br interactions result in dimeric associations in the crystal structure. There are no further interactions between neighbouring dimer units.
