| Product | 9-Nitro-3-hydroxy-2-phenylthiazolo[2,3-a]-phthalazin-4-ium hydroxide | HCID 19913654 | — |
Reaction Steps
0.41 g of 7-nitro-1(2H)-phthalazinethione and 0.37 g of 3-phenyl-2,2-oxiranedicarbonitrile in 10 ml of acetone are heated under reflux for 30 hours. After cooling in an ice-bath, the violet crystals obtained are removed by filtration under suction, washed with ether and dried in vacuo. There is obtained 9-nitro-3-hydroxy-2-phenylthiazolo[2,3-a]-phthalazin-4-ium hydroxide (internal salt) of m.p. 303°-305°.
