Versuchsvorschrift

4-Methyl-pyrimidine (0.1 M) was added to 100 ml of ethanol containing 3.5 g (0.1 M) of HCl. While keeping the reaction mixture at 5° there was added over 60 minutes a solution of 9 g (0.12 M) of ethyl nitrite in 60 ml of ethyl alcohol, whereupon the whole was kept under stirring for 1 hour at room temperature. The thus formed 4-formyl-pyrimidine-oxime hydrochloride was separated by filtration, dissolved in water and the aqueous solution neutralized by adding Na2CO3. The title compound was finally obtained by filtration and drying. M.p. 154°-155°. Yield 71%.
