2-Methyl-2-butene → HCID 69932982, compound

Participants

Reaction Steps

Sodium chlorite (71 mg, 0.78 mmol, 4.0 equiv) was added to a mixture of N-(1-{3-[1-ethyl-5-(4-formylphenoxy)-1H-pyrazol-3-yl]phenyl}-1-methylethyl)-2,2,2-trifluoroethanesulfonamide (97 mg, 0.20 mmol, 1 equiv), 2-methyl-2-butene (1 mL), aqueous sodium dihydrogenphosphate solution (20% w/w, 0.7 mL) and methanol (2.8 mL). The biphasic mixture was stirred for 90 minutes, then was partitioned between ethyl acetate and saturated aqueous sodium chloride solution. The organic layer was dried over sodium sulfate. The dried solution was filtered, and the filtrate was concentrated to afford 4-({1-ethyl-3-[3-(1-methyl-1-{[(2,2,2-trifluoroethyl)sulfonyl]amino}ethyl)phenyl]-1H-pyrazol-5-yl}oxy)benzoic acid. Calcd (M+1)+: 512.1. Found: 512.1.
