Reaction Steps

112 mg (0.24 mmol) of 1-(3-aminomethylphenyl)-3-[3-(4-fluorophenyl)-3-hydroxypropyl]-4-(4-methoxyphenyl)azetidin-2-one are dissolved in 5 ml of methylene chloride and 0.5 ml of triethylamine. At 0° C., 0.5 g of 2,3,4-triacetoxy-1-(acetoxychlorocarbonylmethyl)butyl acetate are added, and the mixture is allowed to thaw to room temperature. After 30 minutes, the mixture is diluted with ethyl acetate and then filtered through silica gel. The solvent is distilled off and the residue is purified by flash chromatography. The product is obtained as an amorphous solid: C42H47FN2O4 (822.84) MS (ESI): M+=823.3.
