Reaction Steps

To a suspension of 250.8 g (1.5 moles) of 2-mercaptobenzothiazole in 1500 ml of methanol are added 112.8 ml (1.5 moles) of 37% aqueous formaldehyde, followed by the dropwise addition, with stirring, of 362.4 g (1.5 moles) of bis(2-ethylhexyl)amine. The mixture is stirred for 15 hours at 50° C. and then concentrated by evaporation in vacuo, affording as residue 618 g of 3-[bis(2-ethylhexyl)aminomethyl]benzothiazoline-2-thione as a reddish brown oil
