A mixture of 11.2 g (0.05 m) of dibenzoylmethane, 16.1 g (0.05 m) of 6-(2-chloro-4-methoxyphenoxy)hexyl bromide, 20.6 g (0.15 m) of milled potassium carbonate, 2.0 g of potassium iodide and 250 ml of 2-butanone was heated at reflux for 18 hours. The reaction mixture was filtered hot and concentrated to a brown oil. The latter was stirred with cold ether and seeded with a sample of the desired product having the m.p. 69°-70° C. The solid product thus obtained was collected to afford 9.0 g of 2-benzoyl-8-[2-chloro-4-methoxyphenoxy]-1-phenyl-1-octanone; MIC=3 microg/ml (herpes 2).
