反応手順
5-Chloro-N-(5-chloro-1,3-thiazol-2-yl)-N-(2,4-dimethoxybenzyl)-2,4-difluorobenzenesulfonamide (Preparation 655) and tert-butyl 3-(5-chloro-2-hydroxyphenyl)azetidine-1-carboxylate (Preparation 237) were stirred in dichloromethane (2 ml) and trifluoroacetic acid (1 ml) to prepare the title compound using Method F above but where the N,N-dimethylformamide was replaced with dimethyl sulphoxide. The crude product was concentrated in vacuo and purified by preparative HPLC to afford the title compound.
