Abstract
The title compounds are prepared by the reaction of a 2-alkyl-2-oxazoline with hydrogen sulfide in a continuous process wherein both reactants are maintained in the liquid phase throughout the reaction by the use of superatmospheric pressure. This continuous process reduces the reaction time substantially compared to prior art process and also reduces the quantity of by-products.
