Versuchsvorschrift

Charge a 5 L steel pressure vessel (autoclave) with 4,6-dichloro-2-methylpyrimidine (400 g, 2.45 mol) and ammonium hydroxide (2.8 L) at RT. Heat the reaction to 90° C. for 5 h. Cool the reaction mixture to RT and then filter the solid through a Buchner funnel. Wash the filtercake with water (200 mL) and hexane (200 mL) and then dry under vacuum to afford the title compound as a white solid (290 g, 82%). LC-ES/MS m/z 144.0 (M+1).
