Novel alkylaminopropanol derivatives of 2-methyl-5-(2-hydroxystyryl)-1,3,4-thiadiazole and their addition salts with acids, their preparation, and pharmaceutical formulations, containing these compounds, which may be used for the treatment of coronary diseases of the heart, of hypertonia and of cardiac arrhythmias.
2-Methyl-5-(2-hydroxystyryl)-1,3,4-thiadiazole of the formula ##STR1## and processes for its preparation by condensing salicylaldehyde with 2,5-dimethyl-1,3,4-thiadiazole or 2-methyl-5-(triphenylphosphine-methylene)-1,3,4-thiadiazole. 2-Methyl-5-(2-hydroxystyryl)-1,3,4-thiadiazole is a valuable intermediate for the preparation of pharmacologically active compounds; for example the alkylamino-hydroxypropyl ethers can, because of their .beta.-sympatholytic action, be used as drugs for the treatment of coronary diseases of the heart, cardiac arrhythmias and hypertonia.
