실험 절차

To a stirred suspension of Step 1 intermediate (4.2 g, 19.98 mmol) in a mixture of 50% aqueous acetic acid (100 ml) and ethanol (100 ml) was added iron powder (5.3 g, 99.9 g atom) and the mixture was refluxed for 3 h. The mixture was cooled to room temperature and filtered through a celite bed. The filtrate was concentrated and the residue obtained was diluted with ethyl acetate and washed with water (2×50 ml) and dried over anhydrous sodium sulfate. The solvent was evaporated to give 3.2 g of the product as a brown oil; 1H NMR (δ ppm, CDCl3, 300 MHz): 7.15-7.07 (m, 1H); 6.62-6.55 (m, 2H); 5.99-5.82 (m, 1H); 5.05-4.95 (m, 2H); 3.86 (s, 3H); 3.53 (d, J=6.0, 2H).
