| description | 1,244,514. 2 - Aminoalkylpyrrolidines. SOC. D'ETUDES SCIENTIFIQUES ET INDUSTRIELLES DE L'ILE - DE - FRANCE. 13 Feb., 1969 [16 Feb., 1968], No. 7934/69. Heading C2C. 2 - Aminoalkylpyrrolidines of the formula in which R 1 represents an alkylene radical and R 2 represents an alkyl or alkenyl group, are prepared by hydrolysing the novel phthalimido derivatives of the formula preferably in the presence of an acid or base. The N-pyrrolidinylalkylphthalimides are prepared by reacting a haloalkyltetrahydrofuran of the formula where X 1 is halogen, with an alkali metal salt of phthalimide to give the novel product of the formula which is reacted with a hydrogen halide or an alkali metal halide in the presence of an acid to obtain a dihaloalkylphthalide of the formula in which X 2 is halogen, which is condensed with an amine R 2 NH 2 to obtain the required pyrrolidine derivative. Examples relate to the preparation of compounds in which R 1 is methylene and R 2 is ethyl, allyl, propyl, isopropyl and butyl. |
