ConditionsYield
With N-ethyl-N,N-diisopropylamine; N-[(dimethylamino)-3-oxo-1H-1,2,3-triazolo[4,5-b]pyridin-1-yl-methylene]-N-methylmethanaminium hexafluorophosphate In N,N-dimethyl-formamide at 10 – 30℃; for 5h;83.4%
With N-ethyl-N,N-diisopropylamine; N-[(dimethylamino)-3-oxo-1H-1,2,3-triazolo[4,5-b]pyridin-1-yl-methylene]-N-methylmethanaminium hexafluorophosphate In N,N-dimethyl-formamide at 20℃;1.1 g
Experimental Procedure
DMF (50 mL), (1S,2S)-2-fluorocyclopropanecarboxylic acid (425 mg, 4.1 mmol), HATU (2.1 g, 5.58 mmol) and DIEA (1.44 g, 11.16 mmol) were successively added to compound 4a (1.0 g, 3.71 mmol), and the mixture was stirred at room temperature for 5 h. The reaction was quenched by adding water, extracted 3 times with ethyl acetate and washed twice with saturated brine. The organic phase was dried and concentrated, and the residue was separated and purified by silica gel column chromatography (eluent: EA/PE=1/2) to obtain 117E (1.1 g, 83.4%). LC-MS (ESI): m/z=356.3 [M+H]+.
