Sodium Carbonate → HCID 66705251, compound

Participants

Reaction Steps

(3R,4S)-N-Cyclopropyl-4-(tert-butyldimethylsilyl)oxymethyl-1-[(1S)-1-phenylethyl]pyrrolidine-3-carboxamide (7.00 g) was dissolved in toluene (70 mL). A borane/dimethyl sulfide complex (2.20 mL) was added and the mixture was refluxed for 5 hours while being stirred. Subsequently, the reaction was allowed to cool to room temperature, followed by addition of a 10% aqueous solution of sodium carbonate (42 mL) and stirring at 100° C. for 1 hour. The toluene layer was separated, washed with water (2×30 mL), dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluant: hexane: ethyl acetate=4:1) to give (3S,4S)-4-(tert-butyldimethylsilyl)oxymethyl-3-cyclopropylaminomethyl-1-[(1S)-1-phenylethyl]pyrrolidine as a colorless oil (4.78 g).
