実験手順

Methylamine (2M in methanol, 20.0 mL, 40.2 mmol) was added dropwise to isobutylisothiocyanate (2.00 mL, 16.5 mmol) during 15 minutes at room temperature. The reaction mixture was heated to reflux for 3.5 h and the solvent was evaporated off to give the title compound (2.37 g, 98%) as a colourless oil.
