Sodium Hydroxide → (1-Benzylpyrrolidin-3-yl)methanol

Participants

Reaction Steps

Red-Al (160 mL of a 3.5 M solution in toluene, 560 mmol) was added to a solution of 1-benzyl-5-oxo-pyrrolidine-3-carboxylic acid (20 g, 91 mmol) in dry THF (650 mL) under argon. The reaction mixture was refluxed for 2.5 h and then poured onto a mixture of crushed ice and NaOH (20%). The phases were separated, the aqueous phase was extracted with toluene and the combined organic phases were dried and concentrated under reduced pressure to give 17.9 g of the crude product as a yellow oil.
