2-Aminothiazole → 1-Benzyl-3-thiazol-2-yl-thiourea

Participants

Reaction Steps

A solution of benzyl isothiocyanate (1.5 g, 10 mmol) and 2-aminothiazole (1.0 g, 10 mmol) in N,N-dimethyl-formamide (25 mL) was heated at 100° C. for 12 h. The reaction was cooled to room temperature, poured into ethyl acetate, washed with water, 1N aqueous HCl, water, saturated sodium bicarbonate, and brine. The organic layer was concentrated and the residue recrystallized twice from ethyl acetate to provide 1.15 g (46%) of the title product:
