Sodium borohydride → (S)-tert-butyl 3-(1-hydroxyethyl)pyrrolidine-1-carboxylate

Participants

Reaction Steps

To a solution of (S)-tert-butyl 3-acetylpyrrolidine-1-carboxylate in methanol (10 mL) was added sodium borohydride (114 mg, 3.0 mmol) at 0° C. The reaction mixture was stirred at ambient temperature for 2 hours then quenched with saturated ammonium chloride solution and extracted with dichloromethane. The combined extracts were dried over magnesium sulfate, filtered, and concentrated to give the title compound for the next step.
