YieldReaction ConditionsOperation in experiment
A mixture of 2-(1 H-pyrazol-3-yl)-1 H-isoindole-1 ,3(2/-/)-dione (for a preparation see Intermediate 28)(3 g, 14.1 mmol) and potassium carbonate (2.92 g, 21.1 mmol) in DMF (30 ml) was stirred under nitrogen at ambient temperature for 5 min. To the pale yellow suspension was added 1-(bromomethyl)-4-chloro-2- (trifluoromethyl)benzene (3.85 g, 14.07 mmol, Alfa Aesar). The mixture turned to a colourless suspension. The reaction mixture was stirred at ambient temperature under nitrogen overnight. The reaction mixture was diluted with DCM (50 ml) and water (50 ml). To the emulsion was added brine (30 ml). The resulting phases were separated and the aqueous layer further extracted with DCM (50 ml). The combined organic extracts were filtered through a hydrophobic frit and the solvent removed in vacuo to give 2-(1-[4-chloro-2-(trifluoromethyl)phenyl]methyl}-1 H-pyrazol-3-yl)-1 H- isoindole-1 ,3(2H)-dione (6.14 g) as an off-white gum.

YieldReaction ConditionsOperation in experiment
Example 80: Lambda/-(1 -( r4-chloro-2-(trifluoromethyl)phenyllmethyl)-1 H-pyrazol-3-vD- 2,6-difluorobenzamide; To a solution of 2,6-difluoro-Lambda/-1/-/-pyrazol-3-ylbenzamide (for a preparation see Intermediate 9)(3 g, 13.4 mmol) in THF (30 ml) was added 1.0 M lithium bis(trimethylsilyl)amide in THF (13.5 ml, 13.5 mmol, Aldrich). The resulting orange solution was stirred at ambient temperature under nitrogen for 30 min. To the reaction was added a solution of 1-(bromomethyl)-4-chloro-2- (trifluoromethyl)benzene (3.7 g, 13.5 mmol, Fluorochem) in THF (5 ml). The resulting orange solution was stirred at ambient temperature under nitrogen overnight. The solvent was removed in vacuo and the residue partitioned between ethyl acetate (125 ml) and aqueous sodium bicarbonate (75 ml). The phases were separated and the organic phase washed with aqueous sodium bicarbonate (50 ml). The combined aqueous phases were washed with ethyl acetate (75 ml). The organic phases were combined, dried, filtered and the solvent removed in vacuo. The residue was loaded in dichloromethane and purified on silica 100 g x 2 using a 0-50% ethyl acetate- cyclohexane. The appropriate fractions were combined and evaporated in vacuo to give the title compound as a yellow solid (2.83 g); LCMS: (System 4) MH+ = 416, tRET = 3.14 min.
