N-octyl-3-[[3-(octylamino)-3-oxopropyl]disulfanyl]propanamide

Conditions: temp:5.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 238 g (1 mol) of dimethyl 3,3′-dithiodipropionamide and 280 g (2.17 mol) of n-octylamine were added into 300 ml of methanol in a 1,000 ml reaction flask, and the reactants stirred at 5° C. for 5 days (under nitrogen atmosphere, if desired). The reaction mixture was then cooled to −10° C., and separated by centrifuging to give 329 g of a solid of N,N′-di-n-octyl-3,3′-dithiodipropionamide (purity >95%, yield 76%). The mother liquor was recycled after methanol was recovered by evaporation. The reaction mixture was then cooled to −10° C. separated by centrifuging
