5-Nitro-furan-2-carboxylic acid 4-(4-methyl -piperazin-1-yl)-benzylamide (65). 5-Nitro-furan-2-carbonyl chloride (438 mg, 2.5 mmol) in CH2Cl2 (10 mL) was added to a mixture of crude amine 45b (410 mg, 2.0 mmol.) in Et3N (1.04 mL, 7.5 mmol) and the mixture was stirred for 12 hrs at room temperature. Reaction was carried out as explained above to afford 481 mg of amide 65 in 70% yields. 1H-NMR (500 MHz, CDCl3): delta 2.41 (3Hs, s), 2.63 (4Hs, t, J=4.88 Hz), 3.27 (4Hs, t, J=4.88 Hz), 4.6 (2Hs, d, J=5.61 Hz), 6.78-6.83 (1H, bs), 6.97 (2Hs, d, J=8.78 Hz), 7.31 (2Hs, d, J=8.78 Hz), 7.33 (1H, d, J=3.90 Hz), 7.41 (1H, d, J=3.90 Hz); 13C-NMR (300 MHz, CDCl3): ppm 41.71, 44.02, 48.06, 53.94, 111.31, 114.88, 115.52, 127.89, 128.91, 147.54, 149.95, 156.61; ESI-MASS: 345.3 (M+1); Anal. Calcd. for C17H2ON4O4: C, 59.29; H, 5.85; N, 16.27. Found: C, 59.16; H, 5.91; N, 16.19.
