Versuchsvorschrift

28% aqueous ammonia (3.1 mL) was added to a solution of 4,6-dichloro-2-(4-fluorophenyl)-5-nitropyrimidine (5.0 g, 17.4 mmol) in tetrahydrofuran (50 mL) at −50° C. until the starting material disappeared. After addition of 3N hydrochloric acid (5 mL) to the reaction solution at the same temperature, the reaction temperature was raised and then the mixture was concentrated in vacuo. Water was added to the residue, and the resulting suspension was filtered, then dried to give the objective compound as a solid (4.05 g, 87%).
