Reaction Steps

To a solution of 3-bromopyridine (12.0 g, 75.6 mmol) and 1-pentyn-3-ol (7.0 mL, 83.2 mmol) in triethylamine (150 mL) were added Pd(PPh3)4 (88 mg, 0.076 mmol) and copper(I) bromide dimethylsulfide (31 mg, 0.15 mmol). The mixture was heated at 70° C. for 5 hr, cooled to room temperature and filtered. The filter cake was washed with EtOAc (30 mL). The combined filtrate was concentrated to give 1-(3-pyridinyl)-1-pentyn-3-ol (12.2 g, 99%) as a dark oil.
