Carbon disulfide (76 g) was added to a mixture of sodium sulfide (55 g) in methanol (80 g) and water (80 g) and kept at 20° C. To this was slowly added N-cyclohexylacrylamide (100 g) maintaining the pot temperature at 20°-30° C. The resulting solution was stirred for an additional 2-3 hour and neutralized with concentrated hydrochloric acid. The organic layer was separated, washed with water and evaporated to dryness to afford 122.6 g of N-cyclohexyl-3-mercaptopropionamide (90.5% yield).
