Reaction Steps

2-Mercaptonicotinic acid (7.8 g, 50 mmol) and 4-(bromomethyl)pyridine hydrobromide (12.6 g, 50 mmol) were suspended in N,N-dimethylformamide (100 mL) under ice-cooling. Triethylamine (21 ml, 150 mmol) was added dropwise to the suspension, and the whole was stirred at room temperature for 6 hours. Water (300 mL) was added to the reaction mixture, then the aqueous layer was washed with ethyl acetate (100 mL). 2 N hydrochloric acid was added to the aqueous layer to adjust to pH 7, and the precipitated solid was filtered off. The solid was washed with water and diethyl ether, and dried at 50° C. under reduced pressure to give 7.5 g of the title reference compound as a gray solid. (Yield 61%)
