Abstract
1346791 Phthalimides DELMAR CHEMICALS Ltd 18 Jan 1971 [21 Jan 1970] 2240/71 Heading C2C The invention comprises novel phthalimides of the Formula II wherein X is Cl or Br, and R 1 and R 2 each are H or alkyl and the conversion of the above compounds in which R 1 and R 2 are alkyl into benzamides of the Formula I wherein R is alkyl and Z is tertiary aminoalkyl, by reacting the said compounds under substantially anhydrous conditions with diamines of the formula ZNH 2 . The compounds of Formula II above are prepared by reacting the appropriate amines with phthalic anhydride, followed by or preceded by, esterification, alkylation and/or bromination or chlorination. Methyl 2-methoxy-4-phthalimidobenzoate is obtained by methylating methyl 4-phthalimidosalicylate, resulting from the reaction of phthalic anhydride on methyl 4-aminosalicylate, obtained by esterifying 4-aminosalicyclic acid. The first named compound may also be obtained by reacting dimethyl sulphate with 4-phthalimidosalicylic acid resulting from the reaction between phthalic anhydride and 4-aminosalicylic acid. Ethyl and isopropyl 4-aminosalicylate, ethyl and isopropyl 4-phthalimidosalicylate, and ethyl and isopropyl 2-methoxy-4-phthalimidobenzoate are obtained by similar processes. N – (2 – Diethylaminoethyl)phthalimide is obtained as a by-product in the reaction between N,N-diethylethylenediamine and methyl 5- chloro-2-methoxy-4-phthalimidobenzoate. Reference has been directed by the Comptroller to Specification 994,023.
