    "3. A heteroaromatic amine derivative of formula ##STR15## wherein A is a carbonyl or thiocarbonyl group; B is a methylene group; E is an n-propylene group; G is a methylene, ethylene, n-propylene, n-butylene or n-pentylene group; R 1 and R 2, which may be identical or different, are hydrogen atoms, methyl or methoxy groups; R 3 is a hydrogen atom, a methyl or allyl group; n is 0, and Het is a benzo[b]thien-2-yl, benzo[b]thien-3-yl, 6-hydroxybenzo[b]thien-3-yl, 6-methoxy-benzo[b]thien-3-yl, 5,6-dimethoxy-benzo[b]thien-3-yl, 2,5-dimethyl-benzo[b]thien-3-yl, 5-methoxy-benzo[b]thien-2-yl, 6-methoxy-benzo[b]thien-2-yl, 6-methylmercapto-benzo[b]thien-3-yl, 6-methylsulphinyl-benzo-[b]thien-3-yl, 6-methylsulphonyl-benzo[b]thien-3-yl, 6-methylsulphonyloxy-benzo[b]thien-3-yl, 6-ethoxycarbonylmethoxy-benzo[b]thien-3-yl, 6-carboxymethoxy-benzo[b]thien-3-yl, 6-dimethylamino-benzo[b]thien-3-yl, 6-methylsulphonylamino-benzo[b]thien-3-yl, 6-acetamino-benzo[b]thien-3-yl or benzo[b]-thien-4-yl group; or n is 0 or 1, and Het is a thien-2-yl, thien-3-yl, 5-methyl-thien-2-yl, 2-methyl-thien-3-yl, 3-methyl-thien-2-yl or 2,5-dimethyl-thien-3-yl group; the enantiomer, diastereomer or acid addition salt thereof.",
    "4. The heteroaromatic amine derivative as recited in claim 3 wherein R 1 and R 2, which may be identical or different, are methyl or methoxy groups; R 3 is a hydrogen atom or a methyl group; n is 0, and Het is a benzo[b]thien-2-yl or benzo[b]thien-3-yl group; or n is 0 or 1, and Het is a thien-2-yl or thien-3-yl group; the enantiomer, diastereomer or acid addition salt thereof.",
