Reaction Steps

1-(4-Benzyloxy-3-methoxy-phenyl)-ethanone (24.61 g, 96 mmol) was dissolved in acetic acid (100 ml) and the mixture was cooled to 10° C. Nitric acid fuming (Fluka ID 84392, 100%, 10 ml, 240 mmol) was added dropwise to the cooled solution over 2 hours. The reaction mixture was allowed to come to room temperature and stirred for 16 hours. The reaction mixture was poured into water (400 ml). The precipitate was filtered, washed with water, then taken up in sodium hydrogencarbonate saturated aqueous solution (300 ml) and stirred for 2 hours. The precipitate was filtered, washed with water and dried. The raw product was recrystallized fromethyl alcohol (1000 ml) to give 18.25 g of product [B]. Yield 65%.
