To a solution of crude N-(4-methoxyphenyl)-2-oxiran-2-ylacetamide (10) in ethanol (2.5 mL) was added triethylamine (0.5 mL), followed by N-(2,6-dimethylphenyl)-2-piperazinylacetamide, a compound of formula (4) (150 mg), and the mixture was heated to reflux for 18 hours. Solvent was removed from the reaction mixture under reduced pressure, and the residue purified by column chromatography on silica gel, eluting with 5% MeOH/dichloromethane, to give 4-(4-{[N-(2,6-dimethylphenyl)carbamoyl]methyl}-piperazinyl)-3-hydroxy-N-(4-methoxyphenyl)butanamide, a compound of Formula I as an off-white solid.
