Reaction Steps
To a solution of pyridazine-4-amine (1.73 g, 18.2 mmol) and pyridine (4.41 ml, 54.6 mmol) in tetrahydrofuran (100 ml) was added 2,2,2-trichloroethyl chloroformate (3.76 ml, 27.3 mmol) was added, the mixture was stirred for 1.5 hours with ice-cooling, the reaction mixture was poured into ice-water and the mixture was extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure to obtain the desired product (218 mg, 4.4%) as a solid.
