実験手順
To a stirred room temperature suspension of 4-methylthiosemicarbazide (7.9 g, 7.5×10-2 mole) and CHCl3 (190 ml), 2-fluorobenzoyl chloride (9.4 ml, 7.9×10-2 mole) was added dropwise. After stirring overnight at room temperature, the precipitate was collected by filtration and the product was washed with two portions of Et2O. Drying by suction gave a colorless powder which was used without further purification in the subsequent cyclization step.
