実験手順
A mixture of 2-amino-5-bromo-4-chlorobenzaldehyde (5 g, 21.46 mmol) and urea (18 g, 300.0 mmol) was stirred at 180° C. for 5 hours. LCMS monitored the reaction was completed. The mixture was cooled to room temperature, washed with water (100 mL×3) and filtered. The filtration cake was dried to get the title compound as a yellow solid (6 g (crude, 100%). MS (ES+) C8H4BrClN2O requires: 258, 260, found: 259, 261 [M+H]+.
