Reaction Steps

This was prepared using the same procedure as for 2-(4-(2-amino-5-bromo-3-nitropyridin-4-yl)piperazin-1-yl)-N-(thiazol-2-yl)acetamide, but here using 4,5-dichloro-3-nitropyridin-2-amine (22 mg, 0.106 mmol), iPrOH (1 mL), DIPEA (0.2 mL) and 1-(1-(pyridin-4-yl)ethyl)piperazine.3×HCl (1.1 eq, 0.116 mmol, 35 mg). Filtration and washing as previously described gave the product (28 mg, 73%) as a yellow solid; δH (500 MHz, DMSO-d6) 1.30 (d, J=6.7 Hz, 3H, CHCH3), 2.42 (s, br, 2H, piperazine NCH2), 2.53 (s, br, 2H, piperazine NCH2), 3.05 (s, br, 4H, piperazine N(CH2)2), 3.54 (q, J=6.8 Hz, 1H, CHCH3), 6.94 (s, br, 2H, NH2), 7.34 (d, J=6.0 Hz, 2H, pyridine H-2 & H-6), 8.04 (s, 1H, chloropyridine H-6), 8.51 (d, J=6.0 Hz, 2H, pyridine H-3 & H-5);
