Reaction Steps

Add triethylamine (2.57 mL, 18.5 mmol) to a suspension of 1.1 g (3.7 mmol) of 4-nitro-2-(piperidin-4-yloxy)-pyridine dihydrochloride in dry dichloromethane (50 mL). Then add 2,6-difluorobenzoyl chloride, 0.512 mL (4.07 mmol). Stir the mixture at room temperature overnight. Add water (50 mL) and separate organic layer. Dry with MgSO4 and filter. Evaporate solvents to obtain 1.22 g (91% yield) of (2,6-difluoro-phenyl)-[4-(4-nitro-pyridin-2-yloxy)-piperidin-1-yl]-methanone as a yellow solid (ES+(m/z)=364 [M+H].
