Reaction Steps

Dimethyl 5-(3-oxopyrrolidin-1-yl)isophthalate (0.1114 g, 0.401 mmol, 1 eq) and NH4Cl (0.086 g, 1.61 mmol, 4 eq) in 5 ml anhydrous MeOH were heated to reflux at 80° C. for 22 h. After cooling to room temperature the solvent was removed in vacuo. The residue was stirred in EtOH and filtered through cotton to remove any insoluble material. Purification via flash chromatography yielded 0.082 g, (0.25 mmol, 63% yield) of dimethyl 5-(3,3-dihydroxypyrrolidin-1-yl)isophthalate.
