Reaction Steps
To a pressure tube was added 1,3-difluoro-2-nitrobenzene (2.8 mL, 26.4 mmol) and 7 N NH3 in CH3OH (10 mL, 70 mmol). The tube was sealed and the mixture was stirred at room temperature for 5 days. The solution was diluted with H2O, extracted with CH2Cl2, and the combined extracts were washed with brine, dried over Na2SO4, filtered and concentrated to give an oil. The oil was triturated with hexane and the resulting orange solid was collected by filtration to give the title compound (2.1 g, 51%).
