Reaction Steps

130 mg of 3-[3-(4-fluorophenyl)-3-hydroxypropyl]-1-[4-(4-fluorobutoxy)phenyl]-4-(4-methoxyphenyl)azetidin-2-one (7) were dissolved in 6 ml of absolute methanol. 120 mg of N-methyltaurine in 2 ml of water and 60 mg of potassium carbonate were then added. The mixture was stirred at 50° C. for 24 h. The reaction mixture was concentrated using a rotary evaporator and the residue was purified by preparative chromatography. Freeze-drying gave the product (50 mg) as an oil.
