Procedure

100 mg of 3-[2-oxo-1-(3-p-tolyl-propyl)-2,5-dihydro-1H-pyrrol-3-yl]-propionic acid methyl ester (40ag) prepared by the above Step 7 was dissolved in methanol solution (0.33 mmol) and then 1.7 M methanolic suspension solution containing NH2OK (0.82 ml, 5.0 mmol) was added thereto at 0° C. and the resulting mixture was stirred for 8 hrs at room temperature. The resulting mixture was neutralized with 0.02 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 methanol and chloroform (1:9) as an eluant to give 50 mg of N-hydroxy-3-[2-oxo-1-(3-p-tolyl-propyl)-2,5-dihydro-1H-pyrrol-3-yl]-propionamide (40ah) (yield: 50%).
