(4-Methanesulfonamidophenyl)boronic acid → N-[2-(2-Methoxy-10,11-dihydro-dibenzo[a,d]cyclohepten-5-ylidenemethyl)-phenyl]-methanesulfonamide

Participants

Reaction Steps

Following the procedures essentially as described in Example 219, below, and using 5-bromomethylene-2-methoxy-10,11-dihydro-5H-dibenzo[a,d]cycloheptene (E/Z mixture, 100 mg, 0.32 mmol) with 4-methanesulfonylaminophenylboronic acid (75 mg, 0.35 mmol) to give 35 mg (27%) of an E/Z mixture of the title compound. MS (ES) 406 (M+1), 404 (M−1). HPLC shows 53% of the E isomer and 44% of the Z isomer.
