In ethanol at 70℃; for 3h; |
[0144] To a solution of 4-iodooxindole (97 mg, 0.375 mmol) in 1 mL EtOH was added 5- dimethyl pyrrole 2-carboxaldehyde (46 mg, 0.484 mmol) and piperidine (2 μL, 0.02 mmol). The yellow mixture was heated and kept at 70 0C for 3 hours. The precipitated product was filtered to separate it from unreacted 3,5-dimethyl pyrrole 2-carboxaldehyde. The retentate was washed with cold ethanol (3 x 2 mL) and dried in a vacuum desiccator to yield 112 mg (89%) of the desired compound. 1H NMR (400 MHz, DMSO-^d) δ: 13.48 (br s, IH) 11.08 (br s, IH), 8.72 (s, IH), 7.49 (d, J= 7.8 Hz, IH), 7.44 (m, IH), 6.92 (m, 3H), 6.41 (m, IH).

71 Synthesis of (Z)-1,3-Dihydro-4-iodo-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (JJJ)
Example 71 Synthesis of (Z)-1,3-Dihydro-4-iodo-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (JJJ) A mixture of 4-iodooxindole (404.1 mg, 1.56 mmol) (see Fukuyama, supra) and pyrrole-2-carboxaldehyde (163.2 mg, 1.72 mmol) (Aldrich) in 2-propanol (6.2 mL) was treated with 2 drops of piperidne. The reaction mixture was heated at reflux for 24 h and then allowed to cool to 23° C., at which time, the reaction mixture was filtered. The solid was washed several times with cold distilled water and then allowed to air dry to provide pure (Z)-1,3-dihydro-4-iodo-3-[(1H-pyrrol-2-yl)methylene]-2H-indol-2-one (341.8 mg, 65%) as a yellow solid which was used without further purification: |
