Participants

Reaction Steps

80.1 A solution of (3S,4S)-3-acetoxy-4-cyano-pyrrolidine-1-carboxylic acid tert-butyl ester (1.00 g, prepared according to example 79.2) in 10 ml of a 2M NH3 solution in MeOH was stirred at 22° C. for 1 h and evaporated. The residue was chromatographed on silica (heptane/AcOEt, 2.5:1) to give (3S,4S)-3-cyano-4-hydroxy-pyrrolidine-1-carboxylic acid tert-butyl ester. Colorless solid. MS 213.3 ([M+H]+)
