Participants

Reaction Steps

2-Amino-4, 6-dichloropyrimidine (3.28 g, 20.0 mmol), 4-nitrophenol (2.78 g, 20.0 mmol), and potassium carbonate (4.15 g, 30.0 mmol) were heated and stirred in dimethylformamide (20 ml) at 100° C. for 3 hours. After returning the reaction solution to room temperature, it was poured into ice water (100 ml) and the precipitated crystals were filtered out, washed with water and blow-dried to obtain the title compound (4.93 g, 18.5 mmol, 92%) as colorless crystals.
