Reaction Steps

Potassium carbonate (9.21 g, 66.6 mmol) was added to a mixture of 2-chloronicotinic acid (5.0 g, 31.7 mol), ethylamine hydrochloride (5.18 g, 63.4 mmol) and copper (I) bromide (450 mg, 3.17 mmol) in N,N-dimethylformamide (50 ml), and the reaction heated at 100° C. for 1.5 hours, then cooled. The resulting solid was removed by filtration, and the filtrate evaporated under reduced pressure. The residual blue/green solid was triturated with acetone, and the resulting solid filtered off and dried in vacuo to afford the title compound.
