실험 절차

A solution of Na2S2O4 (40.04 g, 230 mmol) in water (100 ml) was added to a solution of (E)-tert-butyl 4-(4-bromo-2,6-dimethylphenoxy)-6-(2-(dimethylamino)vinyl)-5-nitropyrimidin-2-yl(4-cyanophenyl)carbamate (28.0 g, 45.9 mmol) in THF (300 ml). The mixture was stirred at room temperature of 2 days. The reaction mixture was concentrated. The residue was washed with water and extracted with ethyl acetate. The organic layer was concentrated and the product was obtained by crystallization from a mixture of water and methanol (18.15 g (mmol, 74%). 1H NMR (CDCl3, 400 MHz) δ 1.33 (s, 9H), 2.05 (s, 6H), 6.73 (d, J=3.8 Hz, 1H), 7.18 (d, J=8.8 Hz, 2H), 7.21 (s, 2H), 7.49 (d, J=8.8, 2H), 7.55 (d, J=3.8 Hz, 1H), 9.09 (s, 1H).
