Chloroform → 2-(4-{[2'-Methyl-4'-(pyrrolidin-1-ylcarbonyl)biphenyl-3-yl]methoxy}benzyl)-1,2,4-oxadiazolidine-3,5-dione

Participants

Reaction Steps

3′-({4-[(3,5-Dioxo-1,2,4-oxadiazolidin-2-yl)methyl]phenoxy}methyl)-2-methylbiphenyl-4-carboxylic acid (10.8 mg) was dissolved in a THF-methanol [1 ml, 4:1 (v/v)] mixed solution, and the solution was added to pyrrolidine (3.2 mg). DMT-MM (12 mg) was added, followed by overnight stirring at room temperature. Thereafter, chloroform was added to the reaction liquid, and the organic layer was washed with 1 M hydrochloric acid. The organic layer was concentrated, and the residue was purified by a fractional HPLC (Waters, product name: Waters SunFire™ Prep C18OBD™ (19×100 mm, 5 μm)) to obtain 2-(4-{[2′-methyl-4′-(pyrrolidin-1-ylcarbonyl)biphenyl-3-yl]methoxy}benzyl)-1,2,4-oxadiazolidine-3,5-dione (8.2 mg).
