Procedure
Following procedures essentially as described in Example 225 and using 2-(10,11-dihydro-dibenzo[a,d]cyclohepten-5-ylidenemethyl)-phenylboronic acid (100 mg, 307 mmol) and 4-bromo-3,5-dimethylisoxazole (81 mg, 0.460 mmol), provides the title compound in 2% yield. MS (ES) 378 (M+H); HPLC shows 94% purity.
