Procedure
To 2.84 g (10.2 mmol) of 1-(3-chloro-2-pyridinyl)-3-(trifluoromethyl)-1H-pyrazole-5-sulfonic acid (i.e. the title material from Step C) in 70 mL of dichloromethane was added 1.96 g (10.2 mmol) of 2-amino-3-methyl-N-(1-methylethyl)benzamide (i.e. the title compound of Step E) 1.78 mL (10.2 mmol) of diisopropylethylamine and approximately 5 mg of 4-(dimethylamino)pyridine. The reaction mixture was stirred for 9 hours, then washed with water and dried (sodium sulfate). The solvent was removed with a rotary evaporator. The residue was purified by MPLC (20-40% ethyl acetate in hexanes as eluant) to afford 0.50 g of the title compound as a foamy white solid melting at 69-72° C.
