A balanced equation for a chemical reaction indicates what is reacting and what is produced, 763111-47-3, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one, cas is 763111-47-3,the phthalazine compound. An updated downstream synthesis route of 763111-47-3 as follows.
General procedure: Compound 4 (400 mg, 1.09 mmol, 1 eq) was dissolved in acetonitrile(10 ml), and then 5a-c (1 eq) and DIEA (2 eq) were added.The mixture was stirred at room temperature for 2 h, and then theprecipitate was filtered, washed with water, acetonitrile and ethylether, and dried to give products 6a-c.4.1.2.1.
