반응 단계
Into a flask equipped with a reflux condenser and magnetic stirrer is charged 50 ml water. Then 28.1 g (0.076 moles) 3-methyl-2-methylthiobenzothiazolium p-toluene sulfonate is dissolved with slight heating. A solution of 9.1 g (0.15 moles) formylhydrazine in 25 ml of water then is added and the mixture is heated at reflux for 15 minutes. The cooled suspension is made acidic until a clear solution results, then made basic. The product precipitates and is filtered, giving 9.1 g (66%), m.p. 134° C.
