To a solution of (R)-1-((R)-1-(4-methoxyphenyl)ethyl)-5-oxopyrrolidine-3-carboxylic acid 1.01 (610 mg, 2.32 mmol) in THF (6 mL) at 0° C. was added BH3-Me2S (2M, 1.74 mL, 3.48 mmol) and the reaction was stirred for 3 hours. Water and EtOAc were added, the layers were separated and the aqueous layer was extracted with EtOAc (4×25 mL). The residue was purified by flash chromatography (EtOAc→15% MeOH in EtOAc) to afford (R)-4-(hydroxymethyl)-1-((R)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one 1.06.
