Synthetic Route of 102359-00-2, These common heterocyclic compound, 102359-00-2, name is 2-Oxoindoline-5-carboxylic Acid, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Example 1 (3Z)-3-[(4-{[2-(diethylamino)ethyl]carbamoyl}-3,5-dimethyl-1H-pyrrol-2-yl)methylene]-2-oxoindoline-5-carboxylic acid (1) A mixture of 2-oxoindoline-5-carboxylic acid (0.708 g, 4 mmol), 3,5-dimethyl-4-(piperidin-1-ylcarbonyl)-1H-pyrrole-2-carbaldehyde (1.030 g, 4.4 mmol) and piperidine (0.2 mL) in EtOH (75 mL) was refluxed for 8 h. The mixture was cooled down to room temperature to provide a precipitate which was filtered and washed with EtOH to provide the target compound 1 (0.980 g, 62.25%) NMR (300 MHz, DMSO-d6) delta ppm: 13.52 (s,1H), 12.5 (bs,1H), 11.19 (s,1H), 8.37 (s,1H), 7.78 (s,1H), 7.77 (d,1H), 6.96 (d,1H), 3.43 (m,4H), 2.29 (s,6H), 1.60 (bs,2H), 1.47 (bs,4H); tR: 3.18 min, MS (ESI): m/z (M+H)+ 394; (M+H)-392.
The synthetic route of 102359-00-2 has been constantly updated, and we look forward to future research findings.
