2,2,3-Tribromopropanal, a reagent which almost became forgotten in the chemical literature after its first application in the 1950s, is used for the one-step transformation of diversely substituted 4-nitro- and 4-methoxyanilines into 3-bromo-6-nitroquinolines and 3-bromo-6-methoxyquinolines. These intermediates are then converted, in one further step, into 3-bromoquinolin-6-ols, which may carry additional substituents at positions 7 and 8.
