Abstract
A solution of 5-nitroisophthaloyl dichloride (1) [1] (3.92 g, 15.8 mmol) and 4-tert-butylbenzhydrazide (2) [2] (6.08 g, 31.6 mmol) in CHCl3 (70 mL) was heated to reflux for 12 h.[...]
Highlights
A solution of 5-nitroisophthaloyl dichloride (1) [1] (3.92 g, 15.8 mmol) and 4-tert-butylbenzhydrazide (2) [2] (6.08 g, 31.6 mmol) in CHCl3 (70 mL) was heated to reflux for 12 h
The solution was heated to reflux for 3 h until evolution of HCl ceased
The precipitate was collected by suction filtration, air-dried, extracted with hot ethanol (200 mL), and dried to afford 3 as a colourless solid (3.11 g, 38%)
