YieldReaction ConditionsOperation in experiment
60% With N,N-dimethyl acetamide; 1,8-diazabicyclo[5.4.0]undec-7-ene; at 150.0℃; (C) To a solution of 971 5-bromothieno[2,3-b]pyridine-2-carboxylic acid (6.6 g, 25.6 mmol) in 973 DMA (50 mL) was added 974 DBU (12.8 g, 84.1 mmol) and the resulting mixture was stirred at 150 C. overnight. After cooling to rt, the reaction was quenched with 444 H2O (100 mL) and the resulting mixture was extracted with EtOAc (3×100 mL). The combined organic extracts were dried (Na2SO4), filtered and concentrated under reduced pressure. The residue thus obtained was purified by silica gel chromatography (0-10% EtOAc/petroleum ether) to afford 975 5-bromothieno[2,3-b]pyridine (3.3 g, 60%), as a white solid. LC/MS: mass calcd. for C7H4BrNS: 212.92, found: 213.8, 215.8 [M+H, M+H+2]+.
