Reaction Conditions:

with iron;acetic acid at 75; for 2.5 h;

Steps:

Synthesis of 5-amino-6-bromoquinoline (28).

Method A: 6-Bromo-5-nitroquinoline (250 mg, 1.0 mmol, 1.0 eq) was dissolved in CH3COOH (5 mL). Fe powder (335 mg, 6.0 mmol, 6.0 eq) was added and the reaction heated to approx. 75 °C for 150 min. Upon cooling, the mixture was filtered through filter paper and celite, and extracted with CH2CI2 (3x20 mL) and a solution of 10% aq Na2CO3 (3x15 mL). The combined organic layers were washed with brine, dried over Na2SO4, and concentrated in vacuo. The crude material was purified by chromatography on silica gel (40% EtOAc/60% hexanes eluant) to provide 5-amino-6-bromoquinoline as a light yellow, amorphous solid (193 mg, 87% yield).
