Preparation of trans-2-Chloro-5-(2,2-dichloro-3-(3,4-dichlorophenyl)cyclopropane-1-carboxamido)-N-(2-methyl-4-(2,2,2-trifluoroacetamido)phenyl)benzamide (F1061)
[0235]
[0236]To a solution of trans-N-(4-amino-2-methylphenyl)-2-chloro-5-(2,2-dichloro-3-(3,4-dichlorophenyl)cyclopropane-1-carboxamido)benzamide (DP1) (0.100 g, 0.179 mmol) and triethylamine (0.037 mL, 0.269 mmol) in dichloromethane (2.0 mL) was added trifluoroacetic anhydride (0.030 mL, 0.215 mmol). The reaction mixture was stirred at room temperature for 18 hours. The reaction mixture was directly loaded onto a Celite® cartridge. Purification by flash column chromatography using 0-40% ethyl acetate / hexanes as eluent afforded the title compound as a white solid (0.080 g, 68%).
[0237]The following compounds were prepared in like manner to the procedure outlined in Example 1:
trans-2-Chloro-5-(2,2-dichloro-3-(3,4-dichlorophenyl)cyclopropane-1-carboxamido)-N-(4-(2,2-difluoroacetamido)-2-methylphenyl)benzamide (F1062)

example 2
Preparation of N-(3-acetamido-2,4-difluorophenyl)-2-chloro-5-((1R,3R)-2,2-dichloro-3-(3,4-dichlorophenyl)cyclopropane-1-carboxamido)benzamide (F1083)
[0276]
[0277]To a solution of N-(3-amino-2,4-difluorophenyl)-2-chloro-5-((1R,3R)-2,2-dichloro-3-(3,4-dichlorophenyl)cyclopropane-1-carboxamido)benzamide (DP2) (0.06 g, 0.104 mmol) in pyridine (0.30 mL, 3.71 mmol) stirred at room temperature was added acetic anhydride (9.77 μl, 0.104 mmol). The reaction mixture was stirred at room temperature for 18 hours, was quenched with water (3 mL), and was extracted with ethyl acetate (10 mL). The organic layer was washed with hydrochloric acid (1 N) and brine before being poured through a phase separator. The organic layer was concentrated under reduced pressure to give a residue. Purification by column chromatography using 0-30% ethyl acetate / hexanes as eluent afforded the title compound as a white solid (0.043 g, 67%).

example 3
Preparation of 2-chloro-5-((1R,3R)-2,2-dichloro-3-(4-fluoro-3-(trifluoromethyl)phenyl)cyclopropane-1-carboxamido)-N-(2,4-difluoro-3-(2,2,2-trifluoroacetamido)phenyl)benzamide (F1169)
[0313]
[0314]Trifluoroacetic anhydride (0.035 g, 0.251 mmol) was added dropwise to a stirred solution of N-(3-amino-2,4-difluorophenyl)-2-chloro-5-((1R,3R)-2,2-dichloro-3-(4-fluoro-3-(trifluoromethyl)phenyl)cyclopropane-1-carboxamido)benzamide (DP9) (0.100 g, 168 mmol), and triethylamine (0.051 g, 0.503 mmol) in anhydrous dichloromethane (3 mL). The solution was stirred for 12 hours at 23° C. and concentrated. Purification by silica gel flash chromatography gave the title compound as a white foam (0.084 g, 69%).
[0315]The following compounds were prepared in like manner to the procedure outlined in Example 3:
2-Chloro-N-(3-(2-chloro-2,2-difluoroacetamido)-2,4-difluorophenyl)-5-((1R,3R)-2,2-dichloro-3-(4-fluoro-3-(trifluoromethyl)phenyl)cyclopropane-1-carboxamido)benzamide (F1170)
