实验步骤: To a mixture of 2-amino-5-bromo-4-chloro-3-nitropyridine (0.252 g, 1.00 mmol) and isopropanol (18 ml) was added 1-(1-phenylethyl)piperazine (0.209 g, 1.10 mmol) followed by diisopropylethylamine (0.20 ml, 1.15 mmol). The reaction mixture was stirred at 45° C. for 20 h, then allowed to cool to room temperature and diluted with isopropanol (10 ml). The resulting precipitate was collected by filtration, washed with isopropanol (3×5 ml), diethyl ether (3×5 ml), and dried. The title compound was obtained as a yellow solid (0.300 g, 74%). 1H-NMR (500 MHz, DMSO-d6) 1.30 (d, J=6.7 Hz, 3H, CHCH3), 2.42 (m, 2H) and 2.54 (m, 2H) (piperazine N(CH2)2), 3.03 (br s, 4H, piperazine N(CH2)2), 3.45 (q, J=6.7 Hz, 1H, CHCH3), 6.95 (s, 2H, NH2), 7.23 (m, 1H) and 7.32 (m, 4H) (PhH), 8.13 (s, 1H, pyridine 6-H); to cool to room temperature The resulting precipitate was collected by filtration washed with isopropanol (3×5 ml), diethyl ether (3×5 ml) dried

实验步骤: The method followed that used to prepare 2-[4-(2-amino-5-chloro-3-nitro-pyridin-4-yl)-piperazin-1-yl]-N-thiazol-2-yl-acetamide (Example 1, step 5), but using 2-amino-4,5-dichloro-3-nitropyridine (0.034 g, 0.16 mmol), isopropanol (3.5 ml), and 1-(1-phenylethyl)piperazine (0.048 g, 0.25 mmol). Purification of the crude product on a silica isolute column using a gradient of ethyl acetate in dichloromethane as eluant (10 to 20%) afforded the title compound as a yellow solid (0.047 g, 81%). 1H-NMR (500 Mz, DMSO-d6) 1.30 (d, J=6.7 Hz, 3H, CH3), 2.40 (br s), and 2.53 (br s, obscured by DMSO peak) (4H, piperazine N(CH2)2), 3.03 (br s, 4H, piperazine N(CH2)2), 3.45 (m, 1H, NCHCH3), 6.98 (s, 2H, 2-NH2), 7.25 (m, 1H) and 7.32 (m, 2H) (ArH), 8.06 (s, 1H, 6-H); Purification of the crude product on a silica isolute column
