Flexible application of Cinnoline-4-carboxylic acid in synthetic route

In every case, we must determine the overall rate law from experimental data and deduce the mechanism from the rate law (and sometimes from other data). you can also browse my other articles about Cinnoline-4-carboxylic acid, CAS: 21905-86-2, if you are interested.

21905-86-2, A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.21905-86-2, name is Cinnoline-4-carboxylic acid. An updated downstream synthesis route of 21905-86-2 as follows.

10764] To a stirred solution of N1-cyclopropyl-5-fluo- robenzene-1,2-diamine mt-i (500 mg, 3.01 mmol) in DMF (5 mE) under an inert atmosphere was added cinnoline-4- carboxylic acid (524 mg, 3.01 mmol), HATU (1.71 g, 4.51 mmol) and diisopropylethylamine (1 mE, 6.02 mmol) at 00 C. The reaction mixture was stirred at room temperature for 16 h. Afier consumption of starting material (by TEC), the reaction mixture was diluted with water (20 mE) and extracted with EtOAc (2×20 mE). The combined organic extracts were washed with water (20 mE), dried over anhydrous Na2SO4 and concentrated under reduced pressure to obtain N-(2-(cyclopropylamino)-4-fluorophenyl) cinnoline4-carboxamide (500 mg, crude) as brown solid used in the next step without further purification.10765] EC-MS: m/z 322.9 [M+H] at 2.71 RT (38.30% purity).
