Application of 6295-87-0, Adding some certain compound to certain chemical reactions, such as: 6295-87-0, name is 1-Aminopyridinium Iodide,molecular formula is C5H7IN2, 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 6295-87-0.
To a dry CH3CN (40 mL) solution of 1-aminopyridinium iodide (1.12 g, 5.02 mmol) was added 4-dimethylaminopyridine (DMAP) (59.9 mg, 0.490 mmol), potassium carbonate (2.08 g, 15.0 mmol), and benzoylchloride (724.4 mg, 5.15 mmol). Then, the reaction mixture was stirred for 7 h at rt. The suspension was concentrated in vacuo. The product was extracted with CH2Cl2 and filtered to remove inorganic impurities. After volatiles were removed under reduced pressure, the crude product was purified by flash column chromatography on Fuji Silysia silica gel FL100D (CH2Cl2/MeOH=20/1) to afford N-benzoyliminopyridinium ylide (2c) as a white solid (668 mg, 3.37 mmol, 67% yield). The spectral data was identical with the reported literatures. 11 1H NMR (400 MHz, CDCl3) delta 8.85 (m, 2H; NC5H2HH2), 8.16 (m, 2H; C6H2H3), 7.92 (m, 1H; NC5H2HH2), 7.68 (m, 2H; NC5H2HH2), 7.42 (m, 3H; C6H2H3).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 6295-87-0, 1-Aminopyridinium Iodide, other downstream synthetic routes, hurry up and to see.
