Reaction Steps
Bis-(4-methoxy-phenyl)-methanone oxime (20 g, 77.82 mmol) is suspended in ammonia (450 mL) and ethanol (90 mL). Ammonium acetate (3.00 g, 38.91 mmol) is added followed by the portion-wise addition of zinc dust (25.29 g, 389.1 mmol). Once the addition is complete the reaction mixture is slowly heated to 50° C. When the effervescence has ceased the reaction mixture is refluxed for 4 hours. The reaction mixture is allowed to cool and ethyl acetate is added (250 mL). The reaction mixture is filtered through Celite® and the phases are separated. The organic layer dried is over MgSO4, filtered and the solvent removed in vacuo to give the title compound. 1H nmr (CDCl3, 400 MHz); 7.25 (d, 4H), 6.80 (d, 4H), 5.10 (s, 1H), 3.75 (s, 6H).
