Procedure
To a solution of 3-tropanol (6.7 g), 2-chloro-4-nitrophenol (8.2 g) and triphenylphosphine (16.1 g) in a mixture of dichloromethane (200 ml) and tetrahydrofuran (50 ml), diethyl azodicarboxylate (9.7 ml) was added dropwise with stirring under ice-cooling, and the resulting mixture was stirred at room temperature overnight and then evaporated in vacuo. The residue obtained was purified by chromatography on a silica gel column using a mixed solvent of dichloromethane and methanol (19:1) as the eluent to afford the title compound (8.5 g, yield: 60%) as a pale yellow amorphous solid.
