실험 절차

BuLi 1.6M (0.106 mol) was added dropwise at −70° C. to a solution of 5-bromo-3-(3-chlorophenyl)-2,1-benzisoxazole (0.0816 mol), obtained in Example A1a, in THF (250 ml) under N2 flow. The mixture was stirred at −70° C. for 15 min. A solution of 4-iodo-N-methoxy-N-methyl-benzamide (0.098 mol) in THF (150 ml) was added dropwise at −70° C. The mixture was stirred at −70° C. for 1 hour then brought to room temperature. The mixture was hydrolysed with water, extracted with EtOAc. The organic layer was separated, dried (MgSO4), filtered, and the solvent was evaporated. The residue (48 g) was crystallized from diethyl ether. The precipitate was filtered off and dried, yielding 16.5 g (44%) of [3-(3-chlorophenyl)-2,1-benzisoxazol-5-yl](4-iodophenyl)-methanone, mp.196° C. (intermediate 35).
