Lithium tri-s-butylborohydride → HCID 66661829, compound

Participants

Reaction Steps

To a solution of benzyl 3-oxo-4-phenylpyrrolidine-1-carboxylate (200 mg, 0.0007 mol) in tetrahydrofuran (2.0 mL, 0.025 mol) under a N2 atmosphere at −78° C. was added L-Selectride® in tetrahydrofuran (1M, 4.1 mL) with stirring. The mixture was stifled at this temperature for 1.5 hours. LCMS indicated that the starting material was consumed and the reaction was quenched with water. The solution was adjusted to pH ˜6 to 7 and was extracted with EtOAc. The organic extract was washed with brine, dried over Na2SO4, filtered and the filtrate was concentrated. The resulting residue was purified with Combiflash, eluting with EtOAc/hexane to afford the product (125 mg). LCMS: m/z 298.0 (M+H+); 320.0 (M+Na+).
