Sodium Hydroxide → N'-Benzoyl-3,4-dichloro-N-(2-methyl-2-propanyl)benzohydrazide

Participants

Reaction Steps

Benzoyl-2-tert-butylhydrazine (4.8 g, 0.25 mole) is stirred vigorously in a two-phase system of 50 mL of methylene chloride and 25 mL of 10% aqueous sodium hydroxide (2.5 g, 0.063 mole) until all dissolves. To this solution is added a solution of 3,4-dichlorobenzoyl chloride (7.3 g, 0.025 mole) in methylene chloride. After stirring the two-phase mixture several hours at ambient temperature, the solid is removed and washed with water and methylene chloride. Recrystallization from 2-propanol gives 7.1 g (78%) of product with mp 234°-235° C.
