Procedure
Following the procedures essentially as described in Example 219, below, and using N-[4-methyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-methanesulfonamide (120 mg, 0.386 mmol) and 5-bromomethylene-10,11-dihydro-5H-dibenzo[a,d]cycloheptene (100 mg, 0.351 mmol) affords 83 mg (61%) of the title compound as a yellow solid. MS (ES) 407 (M+NH4), 388 (M−H); HPLC shows 91% purity.
