Participants

Reaction Steps

To a 0.40 M solution of N,N-dimethylglycine (82.0 mg, 0.800 mmol) in EtOAc (2.00 mL, filtered through activated alumina) were added pentafluorophenol (162 mg, 0.880 mmol) and 1,3-dicyclohexylcarbodiimide (182 mg, 0.88 mmol). The reaction mixture was stirred for 12 h at rt at which time it was filtered (washing with EtOAc) and concentrated. Ester 18 was used immediately without further purification.
