Chemical engineers work across a number of sectors, processes differ within each of these areas, and are directly involved in the design, development, creation and manufacturing process of chemical products. Introduce a common compound, CAS is 21905-86-2, Name is Cinnoline-4-carboxylic acid, belongs to cinnoline compound. 21905-86-2

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).
