Reaction Steps

A mixture of 0.170 g (0.431 mmol) of 3-chloro-N-[5′-chloro-4-(1-hydroxy-ethyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-3′-yl]-benzamide and 0.135 g (0.517 mmol) of triphenylphosphine in methylene chloride (15 mL) is stirred under an atmosphere of nitrogen at 0 C for 5 minutes. To this is added 0.171 g (0.517 mmol) of carbon tetrabromide in several portions. The mixture is stirred at 0 C for 30 minutes and then warmed to room temperature and stirred for 2 days. The mixture is concentrated under reduced pressure and purified by flash silica gel chromatography to give 0.030 g (15%) of N-(4-bromomethyl-5′-chloro-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-3′-yl)-3-chloro-benzamide as a colorless oil.
