反应详情

0.9 g of 4-aminophenoxyacetic acid is suspended in 15 ml of water, and 2.4 ml of 5N NaOH solution are added. After cooling with ice, 0.63 ml of chloroformic acid allyl ester is added over a period of 5 minutes. After removing the cooling bath, the reaction mixture is stirred for 20 minutes at room temperature. The reaction mixture is then washed twice with ethyl acetate, and the aqueous phase is adjusted to pH 2 with 4N HCl and extracted with ethyl acetate. The organic solution is washed with brine and dried over sodium sulphate. The title compound is obtained after evaporating off the solvent.
