実験手順

5-fluoro-2-hydrazinopyridine (295 mg, 2.32 mmol) and 3-(4-methyl-1-piperazinyl)propionic acid (400 mg, 2.32 mmol) were dissolved in DCM (15 mL). EDC (536 mg, 2.79 mmol) and HOBt (31.0 mg, 0.23 mmol) were added and the reaction stirred for 18 h. The mixture was loaded onto an SCX-2 cartridge, which was washed with MeOH product eluted with 2M NH3 in MeOH. Further purification by FCC, using 0-10% [2M NH3 in MeOH] in DCM, afforded the title compound (458 mg, 1.63 mmol, 73%). 1H NMR (400 MHz, CDCl3): 2.32 (3H, s), 2.48-2.54 (2H, t, J 6.0), 2.54-2.70 (8H, br s), 2.69-2.75 (2H, t, J 6.0), 6.60-6.65 (1H, dd, J 8.9, 3.3), 6.75-6.78 (1H, d, J 4.4), 7.25-7.34 (1H, m), 8.02-8.05 (1H, d, J 3.0), 10.50 (1H, s).
