YieldReaction ConditionsOperation in experiment
With sodium hydroxide; stannous chloride; hydrazine hydrochloride; sodium nitrite; In hydrogenchloride; water; Step 2 Preparation of (3-methanesulfonyl-phenyl)-hydrazine To a solution of <strong>[35216-39-8]3-methanesulphonyl-phenylamine</strong> (2.5 g) in 6 mL HCl was added a solution of NaNO2 in 5 mL of H2O at -5 to 0 C. After stirring for 30 min the resulted diazonium salt was poured into a cold solution (-10 to -15 C.) of stannous chloride in 6 ml HCl. The mixture of resulted hydrazine hydrochloride in HCl was stored in the refrigerator overnight. The solution was basified to pH 10, by addition of a 6N solution of NaOH, and extracted with THF. The organic layer was washed, dried over MgSO4, and evaporated to yield 2 g of a light brown solid (3-methanesulfonyl-phenyl)-hydrazine.
