実験手順

1.43 g of 2,5-dichloropyrimidine was dissolved in 20 mol of dimethyl sulfoxide. To this solution, a mixture of 1.50 g of 4-amino-2-nitrophenol and 5 ml of water, and 2.69 g of potassium carbonate were added, and the mixture was reacted in the atmosphere of nitrogen gas at a temperature of from 100° to 110° C. for 2 hours. After the completion of the reaction, the reaction product was poured into water, and extracted with methylene chloride. The extract layer was washed with brine and dried over anhydrous sodium sulfate, and purified by silica gel column chromatography, whereby 0.74 g of 4-(5-chloro-2-pyrimidinyl)-3-nitroaniline having a melting point of from 151° to 152° C., was obtained.
