Reaction Steps

Diethyl acetamidomalonate (1.6 g) was dissolved in 30 ml of dehydrated ethanol and 505 mg of sodium ethoxide and 2 g of 3-bromopropyldodecyl sulfide were added thereto. The mixture was refluxed under a nitrogen atmosphere overnight. The reaction mixture was neutralized with concentrated hydrochloric acid-ethanol (1:11) and concentrated. The concentrate was purified by silica gel column chromatography using hexane-ethyl acetate (5:1→5:2) as an eluent to give 1.722 g of colorless, powdery diethyl 2-acetamido-2-(3-dodecylthiopropyl)malonate.
