Procedure

In a small multi-necked reaction vessel equipped with a magnetic stirrer and gas inlet was placed isopropanol (2 ml), methyl-3-mercaptopropionate (2.0 g, 16.64 mmol), and n-octylamine (2.19 g, 16.94 mmol). The reaction vessel was connected to a trap containing bleach to trap mercaptan vapors, and the reaction was stirred for 19.5 hours while the reaction temperature was held at 30°-35° C. Methylene dichloride was added and the crude product was transferred to a round bottom flask. Evaporation of the solvent under reduced pressure yielded crude N-(n-octyl)-3-mercaptopropionamide as an oily white solid in essentially quantitative yield.
