A series of new 9-phenanthrene aminoalcohols has been prepared in which each compound bears from one to five halogen or halogen-containing moieties. A number of these compounds are extremely active against Plasmodium berghei in the mouse. Some structural requirements for optimal efficacy are considered.

2-nitrobenzaldehyde using N-bromosuccinimide (NBS) or NaBr-NaIO4 in sulfuric acid were examined. In contrast to the reports that 4-bromo-2-nitrobenzaldehyde is formed as a single product in good yield, reactions using NBS gave a number of isomeric mono- and dibrominated products identified by spectroscopical methods and by sodium borohydride reduction to the corresponding benzyl alcohol, and reactions using NaBr-NaIO4
