[EN] METHOD FOR PRODUCING N-[4-METHYLAMINOBENZOYL]-L-GLUTAMIC ACID DIETHYL ESTER [FR] PROCÉDÉ DE FABRICATION D'ESTER DE N-[4-MÉTHYLAMINOBENZOYLE]-L-GLUTAMATE DE DIÉTHYL [JA] N-[4-メチルアミノベンゾイル]-L-グルタミン酸ジエチルエステルの製造方法
Some 4-(substituted phenylsulfonamido)benzoic acids have been synthesized by fly-ash:H3PO3 nano catalyst catalyzed condensation of substituted benzenesulfonylchlorides and 4-aminobenzoic acid in ultrasound irradiation conditions. The yields of the sulfonamides are more than 90%. The synthesized 4-(substituted phenylsulfonamido) benzoic acid derivatives were characterized by their physical constants
