CHEMICAL SYNTHESIS
3-Methyl-1-naphthol (4 g) was treated with solution prepared by diazotizing 5.3 g of sulfanilic acid, the azo derivative was reduced with 16 g of sodium dithionite and the precipitated aminonaphtol, purified by recrystallization from hydrochloric acid containing stannous chloride, yielded 3.4 g of pure 1-amino-2-methyl -4-naphthol hydrochloride (charred at 270deg).
