From 5.75 g (0.25 mole) of metallic sodium and 200 ml of methanol sodium methylate is prepared. 32 g (0.25 mole) of m-chloro-phenol are added, the mixture is refluxed for an hour and evaporated to dryness. The solid residue is suspended in 200 ml of benzene and 88 g (0.25 mole) of chloro acetonyl phosphorane are added. The reaction mixture is refluxed for 3 hours. The sodium chloride is removed by filtration of the hot mixture and the benzene filtrate is evaporated in vacuo. The residual solid crude product is rubbed with 50 ml of ether and the crystals formed are filtered and dried. Thus 97 g of the crystalline title compound are obtained, yield 87.2%.
