Reaction Steps

A solution of (5R)-2-iodo-5-(6-quinolyl)-5-hydroxy-2-pentene (1.74 g) in 30 mL of toluene is cooled to 0° C. and treated with diphenylphosphoryl azide (1.65 g) and 1,8-diazabicyclo[5.4.0]undec-7-ene (0.91 g) for 2 hours. The mix is warmed to ambient temperature and diluted with ethyl acetate. The solution is washed sequentially with water, sat. NaHCO3, and brine, then dried over MgSO4, filtered, and evaporated. The product is purified by SiO2 chromatography.
