1-(3-chlorophenyl)-3-(4-chlorophenyl)prop-2-en-1-one (1.38 g, 5 mmol), Zn dust (1.95 g, 30 mmol), NH4Cl (2.67 g, 50 mmol) were combined in MeOH (10 mL) and water (5 mL). The reaction was refluxed for 4 h, cooled to RT then filtered. The filtrate was concentrated to a residue which was purified by chromatography PE/EA (5:1) to give 1-(3-chlorophenyl)-3-(4-chlorophenyl)propan-1-one (1.15 g, 83% yield) as a brown solid. MH+ 279 and TR=2.025 min.
