Procedure

10 g of [4-(6-bromo-hexyloxy)-phenyl]-(4-bromo-phenyl)-methanone are dissolved in 200 ml of DMF and, after the addition of 14.7 g of sodium azide, the mixture is stirred at 90° C. for 24 hours, filtered and the filtrates are concentrated under reduced pressure. The residue is taken up in 200 ml of ethyl acetate and washed with 10% aqueous sodium hydrogen carbonate solution. The organic phase is dried and concentrated. There are obtained 9.2 9 of [4-(6-azido-hexyloxy)-phenyl]-(4-bromo-phenyl)-methanone, MS: m/e 401 (M+H+, 1Br).
