1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → 2-(4-Benzyloxy-benzoylamino)-2-methyl-propionic acid methyl ester

Participants

Reaction Steps

DIPEA (407 mg, 0.28 mL, 3.15 mmol) was added to a stirred solution of 4-benzyloxy-benzoic acid (200 mg, 0.87 mmol)(prepared by the method as described above) in DMF (2 mL). HOBT (142 mg, 1.05 mmol) and EDCI (201 mg, 1.05 mmol) were then added at room temperature. After 2 minutes, 2-amino-2-methyl-propionic acid methyl ester (161 mg, 1.05 mmol) was added and the resulting mixture was stirred at room temperature overnight. Cold water was then added and filtered the solid precipitated out to afford 200 mg (70% yield) of 2-(4-benzyloxy-benzoylamino)-2-methyl-propionic acid methyl ester. LCMS Purity: 93%.
