Reaction Conditions:
with hydrazine hydrate in ethanol at 85; for 4 h;
Steps:
12 Example 12 3-nitrobenzoylhydrazoneSynthesis
Take a 25ml jar, add 5ml of anhydrous ethanol, 0.53gMethyl 3-nitrobenzoate, stirring, 0.5 g hydrazine hydrate,The reaction was refluxed at 85 °C for 4 h. After the TLC monitoring reaction is over,The ethanol and excess hydrazine hydrate were evaporated under reduced pressure. The silica gel column was separated from the methanol 20:1 by methanol to give an off-white solid of 3-nitrobenzoyl hydrazide 0.51 g.Yield 96.2%.
