Abstract
A process for the preparation of 7-methyl-morpholyl-theophylline, characterized in that theophylline is suspended in an alcohol such as ethanol, in which an equimolar amount of morpholine is added to theophylline with stirring, then drop by drop, a formaldehyde solution, by which the theophylline that remains in suspension is filtered off, because the solution is allowed to stand at room temperature, and then in a refrigerator, to precipitate the product, which is filtered, aspirated to the tube, it is washed with ethanol and then with acetone and because the washed filtrate is air dried.
