実験手順

1.12 g of sodium hydride was added to an N,N-dimethylformamide (35 mL) solution of 3.0 g of 4-amino-2-chloropyrimidine-5-carbonitrile, and stirred at room temperature for 5 minutes. 4.38 g of 2,6-dichlorophenyl isocyanate was added to the reaction liquid, and stirred at room temperature for 1 hour. Ethyl acetate and aqueous 1 N hydrochloric acid solution were added to the reaction solution, and the organic layer was separated. This was washed with saturated saline water, dried with anhydrous magnesium sulfate, and the solvent was evaporated away. The precipitated solid was solidified with a mixed solvent of methanol/ethyl acetate and taken out through filtration to obtain 3.8 g of the entitled compound as a white solid.
