Procedure
To a solution of tert-butyl 4-(2-methyl-4-nitrophenoxy)pyridin-2-ylcarbamate (1.0 g, 2.90 mmol) in dichloromethane (28 mL) was added TFA (4 mL). After stirring at room temperature for 6 hours, the reaction mixture was concentrated under reduced pressure to provide the crude product that was used without further purification.
