Zafirlukast - Preparation Method
Open Data Verified Data
5 Nitro indole and 4-(bromomethyl)-3-methoxybenzoic acid methyl ester dissolved in dioxane, ammonia protection and stirring with the addition of silver oxide, under certain conditions, the yellow oil obtained by the treatment was further crystallized from dichloromethane-hexane to obtain the compound. Under the protection of nitrogen, the compound is added to the suspension of sodium hydride in Tetrahydrofuran, and after a certain period of time, methyl iodide is added to react. The treated compound is dissolved in Tetrahydrofuran, and palladium-carbon catalyst is added, after the reaction, the obtained product and N-methyl morpholine are dissolved in methylene chloride, cyclopentyl chloroformate is added under the protection of nitrogen to react, the compound obtained by treatment is hydrolyzed, The hydrolysate and O-methyl benzene sulfonamide, condensation in dichloromethane in the presence of 1-[3-(dimethylamino) propyl]-3-ethylcarbodiimide hydrochloride and 4-(dimethylamino) pyridine affords zavast.
