Procedure

A mixture of intermediate (6-a) (30 g) in HCl 3 N (220 ml) and methanol (165 ml) was stirred at 100° C. for 5 hours. The mixture was poured into ice and basified with NH3 (aq.). The precipitate was filtered off, washed with water and diethyl ether and dried, yielding 24.9 g (93%) of (4-chlorophenyl)[3-(3-chlorophenyl)-2,1-benzisoxazol-5-yl]methanone (interm. 6-b). The product was used without further purification.
