실험 절차

A solution 2-Chloro-nicotinic acid (3.0 grams, 19.0 mmole), potassium carbonate (6.5 grams, 48.0 mmole) and benzyl bromide (2.8 ml, 24.0 mmole) in dimethylformamide (20 ml) was stirred at room temperature over night. The mixture was poured into 200 ml water and extracted with diethyl ether. The combined extracts were washed with water and brine, dried over MgSO4, filtered, and concentrated to an oil which was purified via flash chromatography on silica using 10% ethyl acetate/hexane as eluent (2.8 g). MW 247.69; MS (m/e) 247 (M+).
