Procedure

The title compound was prepared using a method analogous to that for Preparation 733 below, using 3-cyano-N-(2,4-dimethoxybenzyl)-4-fluoro-N-1,2,4-thiadiazol-5-ylbenzenesulfonamide (Preparation 68) and tert-butyl 4-(5-chloro-4-fluoro-2-hydroxyphenyl)-1H-pyrazole-1-carboxylate (Preparation 743). Purification was by column chromatography (silica, heptane-ethyl acetate 10-60% v/v).
