A method for improving memory or correcting memory deficiency is disclosed, utilizing compounds of the general formula:
wherein each of n¹, n², n³ and n⁴ represent an integer of from zero to 3; each of R¹, R², R³, and R⁴ independently represent a hydrogen atom, a loweralkyl or phehnyl group; R⁵ represents a hydrogen atom or loweralkyl group; Ar represents a phenyl, substituted phenyl, pyridinyl, furanyl, thienyl, methoxy-1H-benzotriazolyl, indolinyl, methoxyindolinyl, methoxypyrimidinyl, amino-methoxypyrimadinyl, 1,3-benzodioxolyl, or naphthalenyl group; X represents oxygen or sulphur; the optical isomers; and the pharmaceutically acceptable acid addition salts, such as hydrates and alcoholates thereof. The dosage effective for this use is from 10 to 1000 nanograms/kg body weight.
