Reaction Steps

18 mg of 3-(1-methyl-2-oxo-2,5-dihydro-1H-pyrrol-3-yl)-propionic acid methyl ester (2g) prepared by the above Step 2 was dissolved in methanol solution (0.1 mM) and then 1.7 M methanolic suspension solution containing NH2OK (0.09 ml, 0.15 mM) was added thereto at 0° C. and the resulting mixture was stirred for 1 hr at room temperature. The resulting mixture was neutralized with 0.03 ml of acetic acid, diluted with 10% methanol/chloroform solution, filtered and concentrated in vacuo. The resulting compound was purified by Silica gel column chromatography with a solvent mixture mixed with EtOAc and methanol (5:2) as an eluant to give 11 mg of N-hydroxy-3-(1-methyl-2-oxo-2,5-dihydro-1H-pyrrol-3-yl)-propionamide (2h) (yield: 59%).
