A mixture of 7 g of 1-methyl-3-cyclohexyl-6-chlorouracil, 18 g of sodium acetate (trihydrate), 7 g of hydroxylamine hydrochloride and 100 ml of methyl-cellosolve is boiled for 1 hour and, when cold, the insolubles are removed by filtration. The filtrate is concentrated and recrystallized from water-ethanol. By the above procedure is obtained 4 g of 1-methyl-3-cyclohexyl-6-hydroxyaminouracil, melting point: 153°-155° C.
