Stage #1: With 1,1'-carbonyldiimidazole In dimethyl sulfoxide at 20℃; for 16 h;
Stage #2: With ammonia In water; dimethyl sulfoxide at 0℃; for 1 h;
Preparation 66-Brom o-nicotinam ideTo a solution of 6-bromo-nicotinic acid (4.8g, 23.8 mmol) in dimethylsulfoxide (20ml) was added at room temperature carbonyldiimidazole (4.8g, 29.6 mmol), and the mixture stirred for 16 hours. To the mixture was added dropwise, with cooling in ice bath, 0.880 ammonia solution (40ml), then the mixture stirred for 1 hour, then poured into water (20ml). The precipitate was filtered, washed with water and dried in vacuo to give the title product as a white solid in 81percent yield, 3.9g.1 HNMR(DMSO-D6, 300MHz) δ: 7.66(br.s, 1H), 7.73(d, 1H), 8.09(m, 1H), 8.15(br.s, 1H), 8.78(d, 1 H). <n="20"/>micro analysis found (percent); C(36.00), 1-1(2.60), N(13.67); C6H5N2Br requires (percent); C(35.84), H(2.51), N(13.93)

Stage #1: With 1,1'-carbonyldiimidazole In tetrahydrofuran at 20℃; for 3 h;
Stage #2: With ammonium hydroxide In tetrahydrofuran at 20℃;
A suspension of 6-Bromonicotinic acid (2 g) and CDI (1.8 g) in THF was stirred at room temperature. After 3 h the NH4OH (8 mL) were added dropwise to the mixture and stirred at room temperature overnight. Then, the solution was concentrated under reduced pressure. Light yellow solid. HPLC purity: 97.1percent. Yield: 79percent.
