Procedure

To a sealable vial was added racemic cis-2-{1-(4-bromobenzyl)-6-[(5-methylpyridin-2-yl)methoxy]-1H-benzimidazol-2-yl}cyclohexanecarboxylic acid (320 mg, 0.56 mmol) RuPhos precatalyst (45 mg, 0.060 mmol), RuPhos (28.5 mg, 0.060 mmol) and 3,3-difluoropyrrolidine hydrochloride (172 mg, 1.20 mmol) and N2 sparged THF (6.0 mL) followed by LiHMDS (3.0 mL, 1.0 M in THF). The resulting reddish mixture was heated to 50° Celsius for 2 h. The reaction mixture was cooled to RT and treated with HCl (3 mL, 0.5 N) and MeOH until homogeneous. The mixture was purified using reverse phase HPLC to afford the title compound (128 mg, 38%).
