   Beispiel 1
1,3-Diäthyl-5-propyl-barbitursäure (1 Mol) wird in überschüssiger Menge Phosphoroxychlorid, das geringe Mengen Phosphorsäure enthält, eingetragen und eine Stunde unter Rückfluss erhitzt. Phosphoroxychlorid wird anschliessend abdestilliert und wie unter Beispiel 2 beschrieben, zu 1,3-Di äthyl-5-propyl-6-chloruracil aufgearbeitet.



   Beispiel 2
1 Mol   1 ,3-Diäthylharnstoff    wird mit 1,2 Mol Propylmalonsäure in Gegenwart von überschüssigem Phosphoroxychlorid 1 Stunde lang unter Rückfluss erhitzt. Das Phos   phoroxychlorid    wird abdestilliert und der Rückstand auf Eis zersetzt. Das gewünschte 1,3-Diäthyl-5-propyl-6-chloruracil fällt in einer Ausbeute von 65% an.

As can be seen in Table II, the uracil derivatives used according to the invention have a high activity against various dermatophytes. It is particularly noteworthy that there have been no uracil derivatives that have a fungistatic effect.

 

   example 1
1,3-diethyl-5-propyl-barbituric acid (1 mol) is added in excess amount of phosphorus oxychloride, which contains small amounts of phosphoric acid, and heated under reflux for one hour. Phosphorus oxychloride is then distilled off and, as described under Example 2, worked up to 1,3-diethyl-5-propyl-6-chlorouracil.



   Example 2
1 mol of 1,3-diethylurea is heated under reflux for 1 hour with 1.2 mol of propylmalonic acid in the presence of excess phosphorus oxychloride. The phosphorus oxychloride is distilled off and the residue is decomposed on ice. The desired 1,3-diethyl-5-propyl-6-chlorouracil is obtained in a yield of 65%.
