実験手順

To a heterogeneous mixture of 2-cyano-3-(trifluoromethyl)-5-nitropyridine A11 (0.075 g, 0.4 mmol) in water (2 ml) was added thiophosgene (50 μl). The mixture was stirred for 2 hours and then washed with water and extracted with chloroform. The organic layer was dried over MgSO4 and concentrated to yield compound A12 (0.087 g, 0.38 mmol, 95%). 1H NMR (400 MHz, CDCl3) δ 7.85 (d, J=2.4 Hz, 1H), 8.72 (d, J=2.4 Hz, 1H); 13C NMR (100 MHz, CDCl3) δ 113.61, 121.04 (q, J=273.1 Hz), 127.41, 130.38 (q, J=4.3 Hz), 131.44 (q, J=34.4 Hz), 133.55, 144.75, 150.30.
