Reaction Steps
A mixture of 1-(4-Benzyloxy-5-methoxy-2-nitro-phenyl)-ethanone (11.94 g 39.6 mmol), ammonium chloride (13.48 g, 250 mmol), zinc powder (65.39 g, 1000 mmol), ethyl alcohol (720 ml) and water (70 ml) was refluxed until completion (5 hours). The mixture was filtered through celite and washed with hot ethyl alcohol. The filtrate was evaporated in vacuum. The residue was taken up in the mixture of chloroform (200 ml), water (200 ml) and the pH of this mixture was set to 8 by adding sodium hydroxide solution. The two layers were separated, the aqueous layer was extracted with chloroform (2×50 ml). The organic layers were combined, washed with water and over Na2SO4, and concentrated to give 9.25 product [α]. Yield 86%.
