Water → 2-Imino-3-(3-trifluoromethylphenyl)-5-ethylthiazoline

Participants

Reaction Steps

A mixture of 2-(t-butoxycarbonylimino)-3-(3-trifluoromethylphenyl)-5-ethylthiazoline (1 g) and trifluoroacetic acid (3 g) in chloroform (20 ml) was stirred at room temperature for 3 hours, followed by addition of water (50 ml) thereto. The resultant mixture was neutralized with potassium carbonate, extracted with chloroform and dried over anhydrous magnesium sulfate. The solvent was removed by distillation under reduced pressure, and the residue was subjected to column chromatography to give 0.3 g of 2-imino-3-(3-trifluoromethylphenyl)-5-ethylthiazoline (Compound (x)).
