Extracurricular laboratory: Synthetic route of Imidazo[1,2-a]pyridine-2-carboxylic acid

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 64951-08-2, Imidazo[1,2-a]pyridine-2-carboxylic acid.

Application of 64951-08-2, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 64951-08-2, name is Imidazo[1,2-a]pyridine-2-carboxylic acid. This compound has unique chemical properties. The synthetic route is as follows.

Step (d) N-{4-[6-fluoro-l-(4-fluorobenzyl)-2,4-dioxo-l,4-dihydropyrido[2,3-d]pyrimidin- 3(2H)-yl]cyclohexyl} imidazo[ 1 ,2-a]pyridine-2-carboxamideTo a mixture of imidazo[l,2-a]pyridine-2-carboxylic acid (91mg, 0.56mmol), HATU (mg, 0.55mmol) and 3-(4-aminocy clohexyl)-6-fluoro- 1 – [4-fluorobenzyl] -pyrido [2,3- d]pyrimidine-2,4(lH,3H)-dione (180mg, 0.46mmol) in Chloroform (5 ml) was added ethyl-di-isopropylamine (0.32ml, 1.87mmol) over a period of 20 seconds. Stirring was continued at ambient temperature for 15 hours. Water was added to the clear solution and the mixture was concentrated under reduced pressure using a rotary evaporator. The obtained solid was filtered, washed with water and dried on the sinter to result in the title compound as an off white solid (120mg, 49%). 1H NMR (300MHz, DMSO-J*): delta 8.75 (IH, d); 8.59 (IH, ddd); 8.40 (IH, s); 8.29 (IH, dd); 7.75 (IH, d); 7.69 (IH, d); 7.34 – 7.43 (2H, m); 7.08 – 7.17 (2H, m); 6.99 (IH, ddd); 5.39 (2H, s); 4.86 (IH, bt); 4.17 (IH, bs); 2.45 – 2.69 (2H, bm); 1.94 – 2.04 (2H, bm); 1.54- 1.80 (4H, m).APCI-MS m/z: 531 [MH+].

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 64951-08-2, Imidazo[1,2-a]pyridine-2-carboxylic acid.
