Methanesulfonamide → HCID 58042509, compound

Participants

Reaction Steps

Methanesulphonamide (89.54 mg, 0.94 mmol) and 1,8-diazabicyclo[5.4.0]undec-7-ene (0.15 mL, 1.03 mmol) were added to 4-methylphenyl-5-chloro-4-(6-(2,2,3,3-tetrafluoropropoxy)-5-(trifluoromethyl)pyridin-3-yloxy)-2-fluorobenzoate (Preparation 263, 475 mg, 0.86 mmol) in acetonitrile (5 mL) and the reaction mixture was stirred for 18 hours at room temperature. The reaction was concentrated in vacuo and the residue was partitioned between ethyl acetate and water, the organic layer was separated, dried over anhydrous magnesium sulfate, filtered and the filtrate was concentrated in vacuo. The crude product was purified by reverse phase chromatography (acetonitrile/water both with 0.1% formic acid) to give the title compound as a white solid (303 mg, 55%).
