Acetic Acid → HCID 20378833, compound

Participants

Reaction Steps

a mixture of 73 g of 1,3-dimethyl-indane, 28 g of trioxymethylene, 64 ml of acetic acid, 41 ml of 85% strength phosphoric acid and 100 ml of concentrated hydrochloric acid is stirred for 24 hours at between 58° and 60° C. The reaction mixture is taken up in a mixture of water and ice and the organic products are extracted with ether. The ether phase is washed with water and dried over sodium sulphate. After evaporation of the ether, the residue obtained is distilled in vacuo. 44.8 g of 1,3-dimethyl-5-chloromethyl-indane are thus obtained in the form of a colourless liquid. Boiling point 1 mm Hg = 110° C.
