Procedure

A suspension of 2.64 g (10 millimoles) of 6-methoxy-7-isopropoxy-2,2-dimethyl-4-chromanone, 4.2 g (20 millimoles) of phosphorous pentachloride and 30 ml of carbon tetrachloride is stirred at 30° C. for 8 hours. The reaction mixture is evaporated and the residue is purified by crystallization from ethanol. Thus 3.8 g of the desired compound are obtained. Yield 60%. Mp.: 80°-85° C.
