2,6-Dimethylphenyl isothiocyanate (16.3 g; 0.1 mol) was added dropwise to 110 mL of 70% aqueous ethylamine solution. The mixture was stirred for 1 hour at ambient temperature. Excess ethylamine was evaporated under a stream of nitrogen. The mixture was diluted with water (100 mL). The solid was collected by filtration and washed with water and dried to give 20.0 g of N-(2,6-dimethylphenyl)-N′-ethylthiourea.
