The methyl 4-(3-acetylphenoxy)-6-dimethylamino-pyrimidin-5-yl-acetate obtained is dissolved in 500 ml methanol, and hydroxylamine hydrochloride (76 g, 1.1 mol) and sodium acetate (107 g, 1.3 mol) are added at 0° C. After stirring for 2 hours at room temperature the product is crystallized by adding water. Filtering and drying gives methyl -[3-(1-hydroximinoethyl)-phenoxy]-6-dimethylamino-pyrimidin-5-yl-acetate in form of yellowish crystals (292 g) having a m.p. of 113°-115° C.
