Sodium hydride → HCID 53255905, compound

Participants

Reaction Steps

A solution of (S)-3-hydroxy-pyrrolidine-1-carboxylic acid tert-butyl ester (500 mg, 2.67 mmol) in anhydrous tetrahydrofuran (10 mL) was added to sodium hydride (60% in mineral oil, 215 mg, 5.34 mmol) gradually, and the resulting mixture was stirred at room temperature for 1 h. 2-Chloro-5-nitropyridine (425 mg, 2.68 mmol) was added, and the reaction mixture was stirred at room temperature for 3 h, then quenched with water, extracted with ethyl acetate, washed with water, dried over anhydrous sodium sulfate, and concentrated to afford (S)-3-(5-nitro-pyridin-2-yloxy)-pyrrolidine-1-carboxylic acid tert-butyl ester as a brown oil (800 mg, 98% yield). The NMR spectrum obtained on the sample is compatible with its structure.
