4-Bromo-1-naphthylamine Usage And Synthesis

Chemical Properties

pale purple fibrous powder

Uses

1-Amino-4-bromonaphthalene is a reagent used in catalytic asymmetric ring opening of meso-epoxides with aromatic amines in water. It can also be used to synthesize of 4-quinolones and quinolone heterocycles.

Synthesis

4-Bromo-1-naphthylamine is synthesised using 1-(acetylamino)-4-bromonaphthalene as a raw material by chemical reaction. The specific synthesis steps are as follows:
The 4-bromo-1-acetamido naphthalene obtained in the first step is dissolved in 100 mL of 95% ethanol, and the mass concentration of 4-bromo-1-acetylaminonaphthalene in the mixed solution is 30%, and the mass concentration is 37% added to the mixed solution. 50mL of concentrated hydrochloric acid, reacted at 80 ° C for 6h, filtered and dried to give 4-bromo-1-naphthylamine.
