Phthalic Anhydride → HCID 12917679, compound

Participants

Reaction Steps

Methyl α-methylthio(p-aminophenyl)acetate (760 mg) and 533 mg of phthalic anhydride were dissolved in 8 ml of acetic acid, and the solution was heated under reflux for 4 hours. The reaction mixture was concentrated under reduced pressure, and 100 ml of an aqueous solution of sodium bicarbonate was added. The mixture was extracted once with 20 ml of methylene chloride, and then twice with 10 ml of methylene chloride each time. The organic layer was dried over anhydrous sodium sulfate, and concentrated under reduced pressure to afford 1.222 g of methyl α-methylthio(p-phthalimidophenyl)acetate as colorless crystals in a yield of 99.5%.
