PROCEDURE

实验过程

A solution of 2-(pyridin-3-yloxy)-ethanol (200 mg) in 5 mL dichloromethane was cooled to 0° C. and treated with carbon tetrabromide (524 mg) followed by triphenylphosphine (415 mg) portionwise. The reaction mixture was stirred at 0° C. for 30 mins then at room temperature for 45 mins. The volatiles were evaporated and the residue purified by silica gel chromatography eluting with 0-100% EtOAc/pentane to give the title compound (204 mg) as a colourless liquid which was used without further purification.
