<p>4-Bromo-2-chloronaphthalen-1-amine is a chemical compound that can be synthesized from acetone and chlorides. The reaction proceeds via a nucleophilic substitution reaction in which one of the chlorine atoms is replaced by an electron pair from acetone. This process occurs when the substituent on the naphthalene ring is not sterically hindered, and it is therefore necessary to use substituents that are electron donors, such as methyl or ethyl groups. 4-Bromo-2-chloronaphthalen-1-amine has been synthesized in Japan by reacting acetone with sodium chloride and bromine at high temperature and pressure. The solvent used was benzene, which was removed after the reaction was complete.</p>
