Reaction Steps
Under nitrogen atmosphere, to a mixture of 25 g of KSCN in 60 ml of dry methanol at -78° C. was added 20 g of Br2 dissolved in 45 ml of methanol. The resulting yellow solution was stirred for 5-10 minutes and 10.1 g of 1-methylpyrrole added in one portion. The mixture was allowed to warm to room temperature and stirred for an additional hour. The mixture was poured into 600 ml of ice-water and extracted twice with 200 ml of methylene chloride. The methylene chloride layer was washed, dried and then concentrated to yield 16.1 g of light yellow oil that turns reddish upon standing.
