Procedure

64.5 mg of 1-(4-fluorophenyl)-3-[3-(4-fluorophenyl)-3-hydroxypropyl]-4-[4-(4-iodobutoxy)phenyl]azetidin-2-one are dissolved in 3 ml of methanol. 60.7 mg of 2-methylaminoethanesulfonic acid are then dissolved in 1 ml of water, and 30.4 mg of potassium carbonate are added. The reaction solution is stirred at 50° C. for 8 h. After concentration using a rotary evaporator at 40° C., the residue is passed over a reverse-phase cartridge (methanol). The resulting crude product is dissolved in hot methanol. The precipitate formed on cooling is filtered off, and the mother liquor is concentrated using a rotary evaporator. The product is obtained as an oil.
