Adding a certain compound to certain chemical reactions, such as: 74764-17-3, N1-(Pyridin-2-yl)ethane-1,2-diamine, 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, Quality Control of N1-(Pyridin-2-yl)ethane-1,2-diamine, blongs to pyridine-derivatives compound. Quality Control of N1-(Pyridin-2-yl)ethane-1,2-diamine
Step 7 5-Amino-6-fluoro-1,4-dihydro-4-oxo-1-(tetrahydropyran-4-yl)-7-[2-(2-pyridylamino)ethylamino]-3-quinolinecarboxylic Acid A mixture of 5-amino-6,7-difluoro-1,4-dihydro-4-oxo-1-(tetrahydropyran-4-yl)-3-quinolinecarboxylic acid (45.0 mg, 0.139 mmol), 2-(2-pyridylamino)ethylamine (29.0 mg, 0.211 mmol), and triethylamine (0.029 mL, 0.209 mmol) in DMSO (1.0 mL) was stirred at 120 C. for 3 h. After dilution of the reaction mixture with 10% MeOH in CHCl3, the whole mixture washed with water, and the washing was extracted with 10% MeOH in CHCl3 two times. The combined the organic layer and the extracts washed with water, dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. Flash chromatography of the residue (10% MeOH in CHCl3) gave 5-Amino-6-fluoro-1,4-dihydro-4-oxo-1-(tetrahydropyran-4-yl)-7-[2-(2-pyridylamino)ethylamino]-3-quinolinecarboxylic Acid (54.0 mg, 88%) as a white powder. 1H NMR (400 MHz, DMSO-d6) delta 1.88-2.02 (4H, m), 3.40-3.60 (6H, m), 3.94-3.98 (2H, m), 4.71-4.78 (1H, m), 6.18 (1H, d, J=6.7 Hz), 6.46-6.51 (2H, m), 6.75 (1H, t, J=6.1 Hz), 6.94 (1H, br), 7.20 (1H, br), 7.34-7.38 (1H, m), 7.98-7.99 (1H, m), 8.47 (1H, s), 15.5 (1H, s). MS (ESI+) m/z 442 (M++H).
The synthetic route of 74764-17-3 has been constantly updated, and we look forward to future research findings.
