Mode opératoire

0.1 mol of 2,3-difluoro-4-(trans-4-pentylcyclohexyl)methoxyphenol, 0.11 mol of butyl bromide and 0.11 mol of potassium carbonate are heated for 16 hours at 100° in 100 ml of dimethylformamide (DMF). After cooling, the inorganic salts are filtered off with suction, the filtrate is concentrated, and water is added. 1-butyloxy-2,3-difluoro-4-(trans-4-pentylcyclohexyl)methoxybenzene is obtained by extraction with dichloromethane.
