HCID 592159295-[5-Fluoro-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid ((S)-2-oxo-pyrrolidin-3-yl)-amideYield 27%

Procedure

To the solution of A4 (334 mg, 0.8 mmol) and DIEA (1 mL) in 20 mL of DMF was added 25b (120 mg, 1.28 mmol). The reaction mixture was stirred at room temperature for several hours. LC/MS was applied to determine completion of the reaction. DMF was evaporated under reduced pressure and the residue was precipitated with 5% diethylamine/methanol (10 mL). The precipitate was collected by filtration, washed with ethanol and dried in vacuum to give title compound as an orange solid (83 mg, 27% yield). 1H NMR (300 MHz, DMSO-d6): δ=13.68 (s, 1H), 10.89 (s, 1H), 7.71-7.82 (m, 4H), 6.82-6.96 (m, 2H), 4.47-4.56 (q, 1H), 3.18-3.25 (m, 2H), 2.42-2.45 (ds, 6H), 2.27-2.39 (m, 1H), 1.92-2.00 (q, 1H). LC/MS: 383.0 [M+H]+.
