反応手順

In Example 4, methacrylamide was added portionwise to oxalyl chloride while stirring, whereby the reaction proceeded with generation of heat. At the stage that addition of 10 g of methacrylamide was completed, the reaction mixture was solidified. Dichloroethane (100 ml) was added thereto. The produced crystals were collected by filtration, washed and dried under reduced pressure to give 2-isopropenyloxazoline-4,5-dione hydrochloride.
