7synthesis methods
-

Yield: 70%

Reaction Conditions:

with sodium dodecyl-sulfate in water for 0.166667 - 0.25 h;

Steps:

1
1-aminonaphthalene-2-thiol was added to 20 ml of water, and 20 mg of sodium dodecylsulfate was added while agitating to obtain a uniform mixture.7.5mmol of acetic anhydride was added for 5 minutes. A precipitation product was obtained in 5-10 minutes. The precipitation product was filtrated and rinsed with 1 ml of water twice followed by drying under vacuum.A non-precipitated reaction mixture was extracted with 25 ml of ethyl acetate twice. The separated organic layer was dried with anhydrous sodium sulfate, and a solvent was removed using a rotatary evaporator under a reduced pressure to obtain 2-methyl naphtothiazole at a yield of 70%.
