To 5-nitropyridin-2-amine (1.00 g, 7.19 mmol) in AcOH was added trimethylsilyl trifluoroacetate (2.111 mL, 12.22 mmol). After stirring for 5 min, triethyl orthoformate (2.155 ml, 12.94 mmol) was added. Azidotrimethylsilane (1.513 mL, 11.50 mmol) was added after stirring for another 5 min. The reaction mixture was stirred at RT overnight, and was concentrated to give the crude solid. The solid was washed with DCM, and dried under vacuum to give title compound. LC/MS: [(M+1)]+=193.19, [(M+1-28)]+=165.19
