With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.23687-26-5,6-Aminoisoquinoline,as a common compound, the synthetic route is as follows.
EXAMPLE II N-(2-Hydroxyethyl)-N’-(isoquinolin-6-yl)-N-[4-[2-(methoxycarbonyl)ethyl]phenyl]-urea To 7.2 g of imidazole and 10.1 g of N,N’-carbonyldiimidazole in 100 ml of dimethylformamide are added dropwise, at a temperature of 0¡ã to 10¡ã C., 9.0 g of 6-aminoisoquinoline in 70 ml of dimethylformamide. After 2 hours stirring at ambient temperature, 15.3 g of N-(2-hydroxyethyl)-4-[2-(methoxycarbonyl)ethyl]aniline in 20 ml of dimethylformamide are added dropwise and the mixture is stirred for 21/2 days at ambient temperature. The mixture is diluted with 750 ml of ethyl acetate and extracted twice with water and saturated saline solution. The organic phase is separated off, dried and evaporated down. The residue is purified by chromatography over a silica gel column using ethyl acetate/methylene chloride/methanol=70:30:10. Yield: 4.8 g (19percent of theory), Rf value: 0.48 (silica gel; methylene chloride/methanol/ethyl acetate=20:1:1), 23687-26-5
The synthetic route of 23687-26-5 has been constantly updated, and we look forward to future research findings.
