Hydrochloric Acid → (E)-3-[4-(benzyloxy)-3-nitrophenyl]-1-(2-hydroxy-5-methyl-3-nitrophenyl)-2-propen-1-one

Participants

Reaction Steps

2-hydroxy-5-methyl-3-nitroacetophenone (200 mg, 1.02 mmol), 4-benzyloxy-3-nitrobenzaldehyde (300 mg, 1.16 mmol) and 3 equivalents of sodium hydroxide (120 mg) were introduced into 80% aqueous ethanol solution and the resulting mixture was stirred for 3 hours at room temperature. The reaction solution was acidified by 2N hydrochloric acid solution and diluted with water. The resulting solid was filtered, washed with large amount of water and methanol, and then dried to give 430 mg (Yield 97%) of the title compound as a yellow solid.
