Triethylamine → HCID 58010887, compound

Participants

Reaction Steps

To a solution of (R)-tert-butyl 3-aminopyrrolidine-1-carboxylate (500 mg, 2.6 mmol) in 5 mL CH2Cl2 was added triethylamine (0.73 mL, 5.2 mmol), and the reaction was cooled to −20° C. (S)-tetrahydrofuran-3-yl chloroformate (525 mg, 3.48 mmol) was added in portions over a period of 10 minutes to the above reaction mixture. After allowing the reaction to warm to room temperature, it was quenched with water and extracted twice with CH2Cl2. The combined organic layers were dried over MgSO4, filtered, and concentrated to afford (S)-tetrahydrofuran-3-yl (R)-1-(tert-butoxycarbonyl)pyrrolidin-3-ylcarbamate. Purification via silica gel chromatography using 0-20% EtOAc in CH2Cl2 gave (S)-tetrahydrofuran-3-yl (R)-1-(tert-butoxycarbonyl)pyrrolidin-3-ylcarbamate (490 mg, 63%). LC/MS: m/z 301.3 (M+H)+ at 2.35 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
