反应详情

To a methanol (100 ml) solution of itaconic acid (100 g), benzoyl chloride (4 ml) was added dropwise under stirring. The reaction solution was stirred at 60-70° C. for 20 minutes and then concentrated under reduced pressure. The resulting solid was recrystallized from a mixed solution of benzene and petroleum ether to obtain 4-methyl itaconate (93 g, melting point: 65-67° C.).
