3-Chloropropionyl chloride → HCID 19980875, compound

Participants

Reaction Steps

17.2 g of AlCl3, 18.5 ml of CS2 and 3.6 ml of β-chloro-propionyl chloride are placed in a stirring flask with a reflux condenser. 7.06 g of methyl 6-phenylcaproate are allowed to drop into this mixture at room temperature within 10 minutes (rinsing is carried out with 4 ml of CS2). The reaction mixture is subsequently stirred for a further 15 minutes, warmed slightly and then cooled. The reaction mixture is then pipetted into a stirred mixture of ice, water and ether. The organic phase is washed neutral with bicarbonate solution and water. After drying over MgSO4 the solvent is removed, 10.2 g of crystalline product identified as methyl p-[β-chloropropionyl]-6-phenyl-caproate are obtained.
