Ammonium Chloride → HCID 22439210, compound

Participants

Reaction Steps

Ammonium chloride (118 mg) and iron powder (1.0 g) were dissolved in a mixed solvent of ethanol (15 ml) and water (5 ml). trans-N-(4-(3-(2-Chlorobenzoyl)-5-ethylthiophen-2-yl)-5-methyl[1,2,4]triazol-3-ylmethyl)-3-(2-nitrophenyl)propenamide (1.07 g) was carefully added under reflux to the reaction mixture, and the mixture was refluxed for 1 hour. The reaction mixture was filtered through Celite, and the filtrate was concentrated. The residue was partitioned between ethyl acetate and water. The organic layer was washed with a saturated aqueous sodium hydrogencarbonate solution and saturated brine, and dried over magnesium sulfate. The solvent was concentrated under reduced pressure. The obtained solid was recrystallized from ethyl acetate to give 0.60 g of trans-N-(4-(3-(2-chlorobenzoyl)-5-ethylthiophen-2-yl)-5-methyl[1,2,4]triazol-3-ylmethyl)-3-(2-aminophenyl)propenamide.
