反応手順

Bromine (3.65 mL, 70.9 mmol) in Chloroform (250 mL) was added dropwise via an addition funnel to a suspension of 2-amino-3-fluorobenzoic acid (10 g, 64.5 mmol) in chloroform (400 mL) at RT. The solution was stirred for 12 hours at which point the resulting slurry was filtered. The solid was washed well with CH2Cl2 and dried under a stream of nitrogen to afford 2-amino-5-bromo-3-fluorobenzoic acid HBr.
