Reaction Steps
A mixture of 1-(3-bromo-2-methylphenyl)-5-oxopyrrolidine-3-carboxylic acid (Intermediate 41-10, 100 mg, 0.335 mmol), EDC (129 mg, 0.671 mmol), HOBT (103 mg, 0.671 mmol) and 28% aqueous ammonia in THF (2 mL) was stirred at rt for 5 h. The mixture was diluted with ethyl acetate, washed with NaHCO3 (aq) and water, and dried and concentrated. The residue was purified by column chromatography (eluting with 90:10 DCM-methanol) to provide 1-(3-bromo-2-methylphenyl)-5-oxopyrrolidine-3-carboxamide as a white solid (26 mg, 26%). Mass spectrum m/z 297, 299 (M+H)+.
