Versuchsvorschrift

A mixture of 4-nitrophenol (3.92 g), 4-chloromethyl-1,3-thiazole hydrochloride (4.0 g), potassium carbonate (8.13 g) and N,N-dimethylformamide (100 mL) was stirred at room temperature for 40 hrs. Water was poured into the reaction mixture, and the mixture was extracted with ethyl acetate-tetrahydrofuran. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated to give 4-[(4-nitrophenoxy)methyl]-1,3-thiazole as colorless crystals (3.38 g, yield 61%). Recrystallization thereof from ethyl acetate-hexane gave colorless prism crystals. melting point: 175-176° C.
