Participants

Reaction Steps

A solution of 1-(tert-butoxycarbonyl)azetidine-3-carboxylic acid (1.3 eq), HOBt (1.3 eq) and EDC.HCl (1.3 eq) in DMF (premixed for 10 min) was added to S)-3-(2-(1-amino-7-oxononyl)oxazol-5-yl)-1-methylquinolin-2(1 H)-one (1 eq), obtained as described above. The mixture was stirred o/n at room temperature. The reaction mixture was diluted with DCM, washed with sat. aq. NaHCO3 solution, brine, dried (Na2SO4), filtered and concentrated. The mixture was purified by flash chromatography on silica, eluting with EtOAc/petroleum ether (from 50% of EtOAc to 100% of EtOAc). MS (ES) C31H40N4O6 requires: 564.67, found: 565.
