Adding a certain compound to certain chemical reactions, such as: 60290-21-3, 4-Chloro-1H-pyrrolo[3,2-c]pyridine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, COA of Formula: C7H5ClN2, blongs to pyridine-derivatives compound. COA of Formula: C7H5ClN2
General procedure: To a solution of 4-chloro-lH-pyrrolo-[3,2-c]-pyridine [60290-21-3] (2.0 g, 13.1 mmol) dissolved in DMF (30.5 mL, 0.944 g/mL, 393.2 mmol) at 0C was added portionwise sodium hydride (1.1 g, 28.8 mmol). The reaction mixture was allowed to reach rt and stirred 45 min, after which it was re-cooled to 0C and l-bromobutane (2.1 mL, 1.27 g/mL, 19.7 mmol) was added dropwise. The mixture was then allowed to reach rt and stirred overnight. NaHC03 sat solution was added and the aqueous phase was extracted with EtOAc. The combined organic extracts were washed with water and brine, then dried over MgS04 and concentrated in vacuo. The crude residue was purified by column chromatography (silica gel; gradient Heptane/EtOAc from 100/0 to 50 /50) to yield 1-1 (2.7 g, 98.7%) as a yellow liquid
The synthetic route of 60290-21-3 has been constantly updated, and we look forward to future research findings.
