Synthesis of betti bases by 1- (α-aminobenzyl)-2-naphthol by 2-naphthol, benzaldehyde and ammonia with the help of mannich reactions by conventional methods like green synthesis. Compounds were synthesised properly. NMR and mass spectroscopy gave good results of the compounds All the compounds were synthesized according to the procedure by varying different aldehydes but we obtained good yield in a nitro substituent when compared to other substituents. All compounds gave promising yields according to the literature.

Key words : betti bases, mass spectroscopy, aldehydes and NMR
