Participants

Reaction Steps

A solution of BBr3 (5 mL, 1 M in DCM) was added to a mixture of racemic cis-ethyl 2-(1-(4-bromo-2,6-difluorobenzyl)-6-methoxy-1H-benzo[d]imidazol-2-yl)cyclohexanecarboxylate (1.5 g, 3.2 mmol) in CH2Cl2 (50 mL) at RT. The reaction mixture was stirred 1 h was and partitioned with H2O (50 mL). The organic layer was separated and concentrated to dryness. The resulting residue was purified by FCC to provide the title compound (110 mg, 87%). MS (ESI): mass calcd. for C23H23BrF2N2O3, 492.09; m/z found, 493.2 [M+H]+.
