HCID 54481294n-Butanephosphonic acid n-butyl-(3-nitrophenyl) ester

実験手順

20 g of n-butanephosphonic acid n-butyl ester chloride are added dropwise to a suspension of 14.3 g of sodium 3-nitrophenolate in 170 ml toluene at 20° C. After 4 hours, the mixture is filtered, the filtrate is evaporated and the residue is distilled in vacuo at 0.1 mm Hg. 16 g of n-butanephosphonic acid n-butyl-(3-nitrophenyl) ester are obtained. After reduction with hydrogen and palladium on charcoal, in isopropanol, at 1 atmosphere pressure, 13.8 g of n-butanephosphonic acid n-butyl-(3-aminophenyl) ester are obtained.
