Isopropylamine → Ethyl isopropylcarbamate

Participants

Reaction Steps

To a solution of ethyl chloroformate (21.7 g, 0.2 mol) in 200 ml ether cooled to 0° C. was added dropwise 35.7 ml of isopropylamine with stirring and cooling. After complete addition of the amine, the reaction mixture was stirred at room temperature for an additional 0.5 hour. The reaction mixture was filtered, and the ether solution was washed with water, and dried over magnesium sulfate. Evaporation of the ether and distillation of the residue in a Kugelrohr apparatus resulted in 22.6 g of the title compound B.p.: 50°-66° C. (bath temperature) at 1.5 mm Hg.
