Versuchsvorschrift

4-fluorobenzoyl chloride (3 mL, 25.4 mmol) was added to 2-(trimethylsilyl)thiazole (2 mL, 12.7 mmol) in dichloromethane (70 mL). The reaction mixture was stirred over night at rt. Dichloromethane was evaporated under reduced pressure, and the crude product purified on a normal phase silica-gel column with 0-40% ethyl acetate in hexane to afford the title compound as white amorphous solid (2.050 g, 77% yield); MS (M+H)+ 208.
