Reaction Steps

EDC (543 mg, 2.83 mmol) was added portionwise to a stirred solution of 5-fluoro-2-hydrazinyl-pyridine (for reference procedure see WO 2010/022076, which is incorporated herein by reference in its entirety; 0.30 g, 2.36 mmol), piperidine-1,4-dicarboxylic acid mono-tert-butyl ester (Aldrich, 649 mg, 2.83 mmol) and HOBt (32 mg, 0.24 mmol) in dry DCM (20 mL). The mixture was stirred at RT for 18 h. The solution was washed with water (2×20 mL), dried (Na2SO4) and evaporated. The residue was triturated (diethyl ether) to give the title compound as an off-white solid (713 mg, 82%). LCMS (Method 1): Rt 2.76 min, m/z 339 [MH+].
