Participants

Reaction Steps

Chlorocarbonylsulfenyl chloride (7.35 g) was added to a suspension of methoxyacetamide (5 g) in toluene (30 cm3). The reaction mixture was stirred and heated at 90°-100° C. for 5 hours, then cooled. The solvent was removed by evaporation under reduced pressure to give a brown gum (6.6 g). M+ =147; 1H NMR (DMSO-d6): δ 3.30(3H,s); 4.30(2H,s) which was used in the next step without further purification.
