実験手順
A mixture of 5-bromo nicotinic acid(1.0 eq.) and CDI (1.1 eq) in DMF (0.25M) was stirred at 20° C. for 5 min and then N′-hydroxy ethanimidamide (1.1 eq) in pyridine (0.6 M) was added. The reaction mixture was stirred at 110° C. for 15 h, cooled to rt and poured into water. The title compound was isolated by filtration as a solid.
