Reaction Conditions

Reaction Steps

To a stirred solution of 4-chloro-2-iodophenol (1.72 g, 6.75 mmol) in anhydrous THF (10.0 mL) were sequentially added (1-methylpiperidin-4-yl)methanol (1.31 g, 10.14 mmol) and triphenyl phosphine (2.66 g, 10.14 mmoL). The reaction mixture was cooled to 0° C., and to it diisopropyl-azodicarboxylate (1.96 mL, 10.14 mmol) was added in drop wise manner. After the addition was over, stirring continued for another 0.5 h at 0° C. and then for 12 h at room temperature. Solvents were removed in vacuum and the residue was purified by silica gel column chromatography, providing Compound 173 (1.85 g, 75%).
