This compound has unique chemical properties. The synthetic route is as follows. COA of Formula: C4HCl2FN2
To a mixture of sodium (450 mg, 19 mmol) in methanol (20 mL) was added a solution of 2,4-dichloro-5-fluoropyrimidine (3.25 g, 19 mmol) in methanol (10ml_). The reaction mixture was stirred at room temperature overnight before being partitioned between water and diethyl ether. The organic phase was separated, washed with brine and evaporated to dryness to give the title compound as an orange oil (80%), which was used in the next step without further purification.1H-NMR delta (400 MHz, CDCI3): 4.1 (s, 3H), 8.2 (s, 1 H).
