실험 절차
To a stirred room temperature solution of 4-methylthiosemicarbazide (10.5 g, 1.00×10-1 mole) and pyridine (250 ml), 2-fluorobenzoyl chloride (11.9 ml, 1.00×10-1 mole) was added dropwise. After stirring overnight at room temperature the excess pyridine was evaporated at reduced pressure first on a rotary evaporator and then at high vacuum. This afforded a mixture of the desired product and pyridine hydrochloride which is used without further purification in the subsequent cyclization step.
