Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 32692-19-6, name is 5-Nitroindoline, A new synthetic method of this compound is introduced below., Formula: C8H8N2O2
1-{1-[6-(5-nitro-2,3-dihydro-indole-1-carbonyl)-pyrimidin-4-yl]-piperidin-4-yl}-1,3-dihydro-imidazo[4,5-b]pyridin-2-one 150 mg (0.47 mmol) TBTU were added to 150 mg (0.44 mmol) 6-[4-(2-oxo-2,3-dihydro-imidazo[4,5-b]pyridin-1-yl)-piperidin-1-yl]-pyrimidine-4-carboxylic acid, 75 mg (0.46 mmol) 5-nitro-2,3-dihydro-1H-indole, 100 muL and (0.712 mmol) triethylamine in 1.5 mL DMF and the mixture was stirred overnight at RT. The reaction mixture was poured onto 30 mL water. The precipitated product was suction filtered and dried at 50 C. in the CAD. Yield: 130 mg (61% of theoretical) ESI-MS: m/z=487 (M+H)+
The synthetic route of 32692-19-6 has been constantly updated, and we look forward to future research findings.
