Potassium Carbonate → HCID 140521633, compound

Participants

Reaction Steps

To a solution of 2-methyl-2-thiopseudourea sulfate (12 g, 278 mmol) and potassium carbonate (12 g, 138 mmol) in toluene (50 ml) and water (50 ml) at 25° C. was added but-3-en-1-yl chloroformate (3.0 g, 134 mmol) then stirred for 2.5 h. The biphasic reaction mixture was separated, and the organic phase was washed with water (2×80 ml), dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated in vacuo to afford but-3-en-1-yl[imino(methylthio)methyl]carbamate (4.0 g, 96%). MS (EI) for C7H12N2O2S: 287 (MH+).
