1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 15850761, compound

Participants

Reaction Steps

Mono-methyl isophthalate (10.0 g, 55.5 mmol), t-butyl n-(2-aminoethyl)carbamate (8.89 g, 55.5 mmol, 1.0 eq) and EDCI (12.2 g, 63.8 mmol, 1.15 eq) were dissolved in 270 mL DCM, followed by the addition of DIPEA (29.0 mL, 166 mmol, 3.0 eq). The reaction was allowed to stir at room temperature overnight. It was then taken up in 100 mL of DCM, washed with a 1:1 solution of 1.0 N HCl in brine, water, and a 1:1 solution of brine in saturated NaHCO3. The organic layer was dried over Na2SO4, filtered and concentrated to afford the product as a light yellow solid (12.81 g, 72%).
