반응 단계
N,N-Diisopropylethylamine (0.69 mL, 0.0040 mol) was added to a mixture of 5-bromopyridine-2-carboxylic acid (400 mg, 0.002 mol), cyclopropylamine (0.16 mL, 0.0024 mol) and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (1.1 g, 0.0024 mol) in N,N-dimethylformamide (9.4 mL, 0.12 mol) at 0° C. and the mixture was stirred overnight at room temperature. The mixture was diluted with ethyl acetate, washed with water and brine successively, dried over sodium sulfate, filtered and concentrated. The product was purified by CombiFlash eluting with CH2Cl2/EtOAc (max.EtOAc 20%). LC-MS: 241.1/243.1 (M+H+)
