To a degassed solution of 7.29 g (15.90 mmol) of (E)-N-((1S,2R)-2-(3-chlorophenyl)-1-(4-chlorophenyl)but-3-enyl)-2-phenylethenesulfonamide (Example 117, Step A) in a 1:1 mixture of DCM (350 mL) and DCE (350 mL) was added Grubbs First Generation (1.20 g, 1.434 mmol). The resulting solution was stirred at 70° C. for 20 hours. After cooling to room temperature, the reaction was concentrated under reduced pressure. Purification by flash chromatography on silica gel (0 to 2% MeOH in DCM gradient) provided the title compound.
