3-amino-N,N-dimethyl-3-sulfanylidenepropanamide

Conditions: temp:55.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A reaction mixture was prepared from 22.4 g. of N,N-dimethylcyanoacetamide, 21 ml. of liquid hydrogen sulfide and 1 ml. of triethylamine. The reaction mixture was placed in an autoclave and the autoclave shaken at about 55° C. for about 12 hours. The reaction mixture was taken from the autoclave and the volatile constituents removed by evaporation. Ethanol was added to the residue, thus producing a crystalline solid. The solid was filtered and the filter cake washed with cold ethanol. Twenty-one grams of 3-amino-3-thioxo-N,N-dimethylpropanamide were obtained melting at 111°-114° C. The compound had the following nmr (CDCl3 +DMSOd6):δ3.07 (doublet, 6H); 3.82 (singlet, 2H); 9.1 (very broad, 1H). A reaction mixture was prepared from 22.4 g the volatile constituents removed by evaporation Ethanol was added to the residue thus producing a crystalline solid The solid was filtered the filter cake washed with cold ethanol

Conditions: temp:55.01; pressure:0.00; stir:; See reaction.notes.procedure_details.
