Ammonium Hydroxide → HCID 17601252, compound

Participants

Reaction Steps

A suspension of 5.21 g (0.02 mole) of 1,2,3,4-tetrahydro-2,3-dioxo-6-quinoxalinesulfonyl chloride and 40 ml of 25% ammonium hydroxide is stirred at room temperature for 6 hours. Then it is filtered, the separated material is washed with water and acetone, filtered, dried, dissolved in a slight amount of hot dimethyl sulfoxide, and the product is precipitated from the solution by adding a slight amount of 2-propanol to it. Thus 0.70 g (15%) of 1,2,3,4-tetrahydro-2,3-dioxo-6-quinoxaline sulfonamide is obtained, m.p.: >360° C.
