Procedure

Aryl Bromide AB1 was prepared by the following procedure. To a solution of 3-bromobenzaldehyde (12.9 g, 70 mmol) in toluene (100 mL) was added 4-(methylsulfonyl)phenylacetic acid (15 g, 70 mmol) and piperidine (2 mL). After overnight refluxing, the mixture was cooled down to r.t. To the slurry thus formed, toluene was added (10 mL). Filtration gave (E)-3-(3-Bromophenyl)-2-[4-(methylsulfonyl)phenyl]-2-propenoic acid as a white solid.
