Procedure

Dibenzylamine (10.2 g) in a dichloromethane (30 mL) solution was added dropwise on an ice bath to a dichloromethane (70 mL) solution of 4,6-dichloro-5-nitropyrimidine (10 g). This was followed by the addition of triethylamine (14.4 mL) and stirring for 1 hour. Water was then added to the reaction mixture and the organic layer was subsequently washed with saturated aqueous sodium chloride solution and dried over anhydrous sodium sulfate. The solvent was concentrated under reduced pressure to obtain the title compound (19.2 g) having the physical property value indicated below.
