Reaction Steps

To 4-hydroxy-3-nitro-N-(trifluoromethylcarbonyl)benzenamine (10.0 g), triphenylphosphine (22.1 g) and 4-hydroxy-N-(t-butoxycarbonyl)piperidine (17.0 g) in THF (30 mL) was added DEAD (13.5 mL) drop-wise. The reaction was stirred at ambient temperature for 1 hour, concentrated and purified on silica gel column (ethyl acetate/hexane, gradient) to afford 4-(N′-(t-butoxycarbonyl)piperidin-4-yl)oxy-3-nitro-N-(trifluoromethylcarbonyl)benzenamine.
