N-(dimethylcarbamothioyl)-3-methylbut-2-enamide

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

Procedure: Was prepared in the same manner as described in General Procedure Example 1b) using 3-methylbut-2-enoyl isothiocyanate (2 g, 14.2 mmol, Eq: 1.00) and dimethylamine solution 2M in THF (7.08 ml, 14.2 mmol, Eq: 1.00). Evaporation of the solvent afforded 1,1-dimethyl-3-(3-methyl-but-2-enoyl)-thiourea (2.239 g/84.9%) as a yellow oil which was used without further purification in the next step. MS: m/e=187.4 (M+H+) Was prepared in the same manner Evaporation of the solvent
