Triphenylphosphine → HCID 57659772, compound

Participants

Reaction Steps

Diisopropyl azodicarboxylate (45 μL, 0.228 mmol) was added dropwise to a stirred solution of triphenylphosphine (60 mg, 0.228 mmol) and N-((3-((4-fluorophenyl)(hydroxy)methyl)-1-(methoxymethyl)-1H-pyrazol-4-yl)methyl)-4-(trifluoromethyl)benzenesulfonamide (45) (90 mg, 0.190 mmol) in THF (5 mL) under nitrogen at 0° C. Reaction was warmed to rt and stirred 16 hr. The reaction was concentrated in vacuo. The resulting crude product was purified via column chromatography using EtOAc/hexane gradients to yield 6-(4-fluorophenyl)-2-(methoxymethyl)-5-(4-(trifluoromethyl)phenylsulfonyl)-2,4,5,6-tetrahydropyrrolo[3,4-c]pyrazole (46) (64 mg, 71%) as a white solid.
