How is (1R,3S,4S)-tert-butyl 3-(6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzo[d]imidazol-2-yl)-2-azabicyclo[2.2.1]heptane-2-carboxylate (CAS: 1256387-87-7) typically synthesized?

This compound is typically synthesized via a multistep process involving the coupling of an azabicycline and a 1,3,2-dioxaborolane derivative under basic conditions. The reaction uses a palladium catalyst and is conducted in the presence of a base such as potassium carbonate. The yield is generally moderate to good, with high selectivity to the desired enantiomer. Detailed procedures can be found in relevant chemical literature.
