Reaction Steps
To a cooled solution (0° C.) of 5-oxo-1-(3-pyrrol-1-yl-propyl)-pyrrolidine-3-carboxylic acid methyl ester in THF, 0.2M LiOH is added and RM is stirred for 3 hours gradually warming to room temperature. Reaction mixture is acidified with 1N HCl and product extracted into ethyl acetate. The organic phase is washed with brine, dried over magnesium sulphate and the solvent evaporated in vacuo to yield 5-oxo-1-(3-pyrrol-1-yl-propyl)-pyrrolidine-3-carboxylic acid.
