Reaction Steps
Benzhydrazide (4.08 g) was dissolved in pyridine (25 mL) and cooled on ice. Tosyl chloride (5.72 g) was added portionwise over 5 minutes. Stirring was maintained at 0° C. for 15 minutes. Stirring at room temperature for 18 hours was followed by pouring into dilute HCl (650 mL). The resultant precipitate was filtered off, washed with water, and recrystallized from hot ethanol/water to afford 6.76 g of product as fine white needles.
