Triethylamine → HCID 57971668、化合物

Monomethyl suberate (25.0 g, 13.3 mmol, 1.0 eq) was dissolved in THF (300 mL) and DCM (300 mL). EDC.HCl (25.46 g, 13.3 mmol, 1.0 eq) was added to the stirred solution, followed by HOBt (17.95 g, 13.3 mmol, 1.0 eq) and triethylamine (48.5 mL, 34.5 mmol, 2.6 eq). O-(1-Isobutoxy-ethyl)hydroxylamine (21.9 mL, 15.9 mmol, 1.2 eq) was added to the viscous solution and the reaction allowed to stir overnight at room temperature. The reaction mixture was concentrated under vacuum, DCM (350 mL) was added and washed with water (250 mL) and brine (200 mL). The organic layer was isolated, dried (MgSO4), filtered and concentrated in vacuo. The product was obtained as a white solid (36.6 g, 91% yield) LCMS purity 88%, m/z 302 (M++H)+. This was used in the next step without further purification.
