Procedure

199 mg of hydroxylammonium hydrochloride were added to a solution of 200 mg of 4-[3-[3-(4-fluorophenyl)-3-hydroxypropyl]-2-(4-methoxyphenyl)-4-oxoazetidin-1-yl]benzonitrile (8) and 0.45 ml of triethylamin in 15 ml of isopropanol. The mixture was stirred at room temperature for 12 h. The reaction solution was extracted twice with ethyl acetate/water. The organic phases were dried over magnesium sulfate and concentrated. This gave the product of molecular weight 463.51 (C26H26F1N3O4); MS (ESI): 464.19 (M+H+).
