Triphenylphosphine → 2-Chloro-5-[(1-methylpiperidin-4-yl)oxy]pyrimidine

To a solution of 100 mg (0.766 mmol) of 4-hydroxy-1-methyl piperidine in 1.5 ml of tetrahydrofuran, 155 mg (1.53 mmol) of di-tert-butyl azocarboxylic acid, 402 mg (1.53 mmol) of triphenylphosphine and 0.170 ml (1.53 mmol) of 2-chloro-5-hydroxypyrimidine were added, and the reaction solution was stirred at room temperature for 1 hour. After completion of the reaction, ethyl acetate was added to the reaction solution and the reaction solution was extracted with 1 N hydrochloric acid. 1 N sodium hydroxide aqueous solution was added to the aqueous layer to make its pH 10 and then the aqueous layer was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride aqueous solution and dried with anhydrous sodium sulfate, and then the solvent was distilled off under reduced pressure to provide 152 mg of the title compound as a white solid (yield: 87%).
