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., 21905-86-2. The reaction mechanism is the process, or pathway, by which a reaction occurs.21905-86-2. An updated downstream synthesis route of 21905-86-2 as follows.
EXAMPLE 5 n-Propyl Cinnoline-4-carboxylate (5) A suspension of 870 mg of 1, and 850 mg of carbonyidimidazole (CDII) in 30 ml of tetrahydrofuran (THF) was stirred at room temperature until CO2 evolution ceased (ca. 30 minutes). After being stirred for 2 hours, the resulting mixture was treated with 320 mg of dry nypropanol and 3 drops of a 0.1 M solution of sodium imidazole in THE. The mixture was held at room temperature overnight, then the solvent was evaporated and the residue was partitioned between water and ether. The etheral extract was washed with saturated sodium bicarbonate solution, then with brine, then dried (MgSO4) and stripped in a rotary evaporator. The residue was chromatographed over silica gel, using a 1:1 v:v mixture of cyclohexane and ethyl acetate as eluent, to give 5, as a yellow oil.
A chemical reaction often occurs in steps, although it may not always be obvious to an observer. Thank you very much for taking the time to read this article.
