Reaction Steps

To a suspension of MOCl5 (8 g) in 50 ml of THF was added 10 ml of H2O and followed by the addition of Zn dust (3 g) 5 minutes later. 5-Nitrobenzo-2,1,3-thiadiazole (1.0 g) was then added to this mixture and the resulting reaction mixture was kept under reflux for 20 minutes. Benzo[1,2,5]thiadiazol-5-ylamine (0.4 g) was isolated by filtration and purified by column chromatography to be used in the next step.
