Abstract
1346792 Benzamide derivatives DELMAR CHEMICALS Ltd 18 Jan 1971 [21 Jan 1970] 48148/72 Divided out of 1346791 Addition to 1346791 Heading C2C Benzamide derivatives of the formula wherein X is Cl or Br, R is alkyl and Z is tertiary aminoalkyl are prepared by removing the phthaloyl group in phthalimido compounds having the formula when R 1 is alkyl and reacting the resulting amino compounds with amines of the formula ZNH 2 . Methyl 5-chloro-2-methoxy-4-phthalimidobenzoate is obtained by chlorinating methyl 2- methoxy-4-phthalimidobenzoate, resulting from the methylation of methyl 4-phthalimidosalicylate, which is made by reacting phthalic anhydride with methyl 4-aminosalicylate, obtained by esterifying 4-aminosalicylic acid. Methyl 2-methoxyphthalimidobenzoate may also be obtained by reacting dimethyl sulphate with 4-phthalimidosalicylic acid, resulting from the reaction between p-aminosalicyclic acid and phthalic anhydride. Reference has been directed by the Comptroller to Specifications 1,146,33 and 994,023.
