Participants

Reaction Steps

To a solution of 0.70 g of 3-chloro-4-(4-hydroxypiperidino)benzoic acid in 15 ml of methylene chloride, 1.5 ml of 2,6-lutidine and 2.7 g of tert-butyldimethylsilyltriflate were added, and the mixture was stirred at room temperature for 2 weeks. To the reaction solution, EtOAc was added, and the organic layer was washed with water and brine and then dried over sodium sulfate. After the evaporation of the solvent, the obtained residue was purified by silica gel column chromatography (eluent:hexane-EtOAc=5:1˜4:1) to obtain 0.90 g of 4-(4-tert-butyldimethylsilyloxypiperidino)-3-chlorobenzoic acid methyl ester.
