Reaction Conditions

Temperature50 °C

Reaction Steps

4.1 g (0.03 mol) of 3H-oxazolo[4,5-b]pyridin-2-one are dissolved in 100 ml of alcohol at 95° C. 2.88 g (0.33 mol) of morpholine and then 3 ml of 30% aqueous formaldehyde solution are added. The mixture is stirred on a water bath at a temperature in the region of 50° C. for one hour 30 minutes, stirring being maintained. The mixture is left to stand for one hour at room temperature. The crystals are drained and recrystallized.
