실험 절차

2,4-Dichloropyrimidine (50 g, 0.34 mol), 2,5-dichloroaniline (54.38 g, 0.34 mol) and concentrated hydrochloric acid (cat. amount) were dissolved in n-butanol (250 ml). The reaction mixture was stirred at room temperature for 12 hours after which the solid that had formed was collected by filtration. The organics were allowed to stand for 48 hours and the solid that formed was collected by filtration, washed with EtOAc and dried to give the title product as a white solid (18.65 g). NMR (300 MHz): 6.82 (d, 1H), 7.31 (dd, 1H), 7.58 (d, 1H), 7.82 (s, 1H), 8.19 (d, 1H), 9.82 (s, 1H); m/z: (ES+) 273.9 (MH+).
