Formaldehyde → 3-(Anilinomethyl)-1,3-benzothiazole-2(3H)-thione

Participants

Reaction Steps

With stirring, 18.63 g (0.2 mole) of aniline are added to a suspension of 33.45 g (0.2 mole) of 2-mercaptobenzothiazole in 120 ml of ethanol, the temperature rising to 30° C. Then 16.4 g (0.2 mole) of 37% aqueous formaldehyde solution are added and stirring is continued for 30 minutes. The precipitate is isolated by filtration and washed with cold ethanol and hexane, affording 47 g of 3-(phenylaminomethyl)benzothiazoline-2-thione which melts at 102°-103° C.
