Reaction Steps

A solution of the crude 4-(2-pyridyl)-1-trityl-1H-imidazole (0.69g) in tetrahydrofuran (14 mL) was treated with 2 N hydrochloric acid (7.2 mL) and heated at reflux for 45 minutes. After cooling the reaction mixture was concentrated in vacuo and the residue was dissolved in dichloromethane (20 mL). The organic solution was successively washed with aqueous 1N sodium hydroxide (10 mL), water (20 mL) and brine (20 mL). The organic solution was then dried over anhydrous sodium sulfate, filtered, and concentrated in-vacuo to afford 0.12 g of crude 4-(2-pyridyl)imidazole, as a sticky white solid.
