Reaction Steps

To a suspension of LiAlH4 (18.33 g, 219.2 mmol) in 200 mL THF, (3R,4R)-1-benzyl-3,4-dihydroxypyrrolidine-2,5-dione (23.1 g, 104.4 mmol) was added and the mixture was refluxed for 12 hours. The mixture was cooled down to room temperature and carefully quenched with 3 mL EtOAc and 3 mL MeOH. Wet silica gel was added to the mixture following by addition of MeOH—CHCl3, 1:1, and the mixture was filtered. The filtrate was evaporated giving the title compound that was used for the next step without additional purification.
