Synthetic Route of 55314-16-4, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 55314-16-4 as follows.
A mixture of 65 g (0.156 moles) of 4-methyl-N-[3-(4-methyl-1H-imidazol-1-yl-5-(trifluoromethyl)phenyl]-3-guanidino-benzamide from step (c), 30.0 g (0.171 moles) of 3-dimethylamino-1-(3-pyridyl)-2-propen-1-one of the formula (VIII) in 650 ml n-butanol was heated at 110-115 C. for 9 hours. Reaction mass was brought to room temperature and the separated solid (70 g) was filtered off. Wet solid was leached with hot water (700 ml) and hot methanol (700 ml) successively. The wet product was dried at 60-65 C. under vacuum to yield compound of formula (I). Yield: 52.1 g (63%) MR: 235-236 C. Purity: 99.0% (by HPLC)
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,55314-16-4, its application will become more common.
