Participants

Reaction Steps

To a solution of 2,6-difluoro-N-(1-{[5-hydroxy-2-(trifluoromethyl)phenyl]methyl}-1H-pyrazol-3-yl)benzamide (for a preparation see Intermediate 42)(75 mg, 0.189 mmol) in DMSO (1 ml) was added potassium t-butoxide (23 mg, 0.205 mmol, Aldrich). The solution was stirred at ambient temperature for 5 min. To the solution was added (bromomethyl)cyclopropane (0.023 ml, 0.245 mmol, Alfa Aesar) and the mixture stirred overnight at ambient temperature under nitrogen. The solution was diluted with methanol (1 ml) and purified by MDAP on Sunfire C18 column (Method B) using Acetonitrile-Water with a Formic acid modifier. The solvent was evaporated in vacuo to give the title compound as a white solid (36 mg); LCMS: (System 4) MH+=452, tRET=3.18 min.
