Versuchsvorschrift

To a stirred solution of 2-((tert-butoxycarbonyl)amino)-3-hydroxypropanoic acid (500 mg, 2.4 mmol) and 6-chloro-4-(isopropylamino)nicotinohydrazide (10) (2.6 mmol, 1.1 equiv.) in DMF (10 mL), DIPEA (12 mmol, 5 equiv.) and HATU (2.6 mmol, 1.1 equiv.) were added and stirred overnight at room temperature. The reaction mass was concentrated under reduced pressure to remove excess of solvent present. Diluted the residue with EtOAc and washed water followed by brine solution. The organic layer was collected, dried over Na2SO4, filtered and concentrated to get tert-butyl (1-(2-(6-chloro-4-(isopropylamino)nicotinoyl)hydrazinyl)-3-hydroxy-1-oxopropan-2-yl)carbamate (53).
