Reaction Steps
38.97 g (121.4 mmol) (2S,4R)-4-hydroxy-1-(naphthalene-2-sulfonyl)-pyrrolidine-2-carboxylic acid were dissolved in 97 ml MeOH and 64.5 ml 1.75 M (112.8 mmol) HCl in MeOH were added and the solution heated to reflux for 3 h and concentrated. Trituration with hexane yielded 41.4 g (quant.) (2S,4R)-4-hydroxy-1-(naphthalene-2-sulfonyl)-pyrrolidine-2-carboxylic acid methyl ester as brown solid, MS: 335 (MH+).
