実験手順

To a solution of 3-amino-6-iodopyridazine (10.0 g, 45.2 mmol) in N,N-dimethylacetamide (100 mL) were added tert-butyl (chloroacetyl)carbamate (14.0 g, 72.4 mmol) and disodium hydrogenphosphate (16.1 g, 113 mmol), and the mixture was stirred at 120° C. for 3 hr. After cooling the mixture to room temperature, water (400 mL) was added to the mixture, and the precipitated crystals were filtrated, and washed with acetonitrile and petroleum ether to give the title compound (10.2 g, 63%) as a green powder.
