Adding a certain compound to certain chemical reactions, such as: 1001413-01-9, 1-(3,4-Difluorobenzyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid, 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, SDS of cas: 1001413-01-9, blongs to pyridine-derivatives compound. SDS of cas: 1001413-01-9
Compound 53.3 (0.094 grams, 0.204 mmol) was dissolved in methanol (5 ml). A scoop of palladium on carbon (Degussa Type ElOl NEAV wet) was added followed by 4.0M HCl p-Dioxane (1 ml). This mixture was placed on a Parr shaker at 40 psi for 48 hours, filtered through Celite, and concentrated. This residue was mixed with Compound 20.2 (54 milligrams, 0.204 mmol), N-(3-dimethylaminopropyl)-N’-ethylcarbodiimide hydrochloride (47 milligrams, 0.245 mmol) and 1-hydroxybenzotriazole monohydrate (38 milligrams, 0.245 mmol), dissolved in N,N-dimethylformamide (2 ml) and diisopropylethylamine (0.178 ml, 1.02 mmol) was added. The reaction was stirred at ambient temperature for 16 hours and then flooded with ethyl acetate, washed with saturated sodium bicarbonate, brine, dried over sodium sulfate, filtered and concentrated to yield Compound 53.4 (2.8 milligrams, 0.006 mmol). ES (+) MS m/e = 461 (M+H). IH NMR (400 MHz, MeOH-d4) delta ppm 4.60 (s, 2 H) 5.14 (s, 2 H) 6.49 (m, 1 H) 6.60 (m, 1 H) 7.11 (m, 2 H) 7.23 (m, 1 H) 7.37 (m, 1 H) 7.83 (m, 1 H) 7.96 (m, 1 H) 8.29 (m, 1 H) 8.40 (m, 1 H) 8.69 (d, J=8.31 Hz, 1 H).
The synthetic route of 1001413-01-9 has been constantly updated, and we look forward to future research findings.
