Phthalimide → HCID 58009522, compound

Participants

Reaction Steps

590 mg of methyl 5-(hydroxymethyl)-1-methyl-1H-pyrrole-2-carboxylate, 770 mg of phthalimide, and 1.83 g of triphenylphosphine were dissolved in 10.0 mL of THF, and 2.75 mL of diethyl azodicarboxylate was added thereto under ice-cooling, followed by stirring at room temperature overnight. The reaction liquid was concentrated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=3:1 to 1:1) to obtain 650 mg of methyl 5-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)methyl]-1-methyl-1H-pyrrole-2-carboxylate.
