1-Pyrrolidineacetic acid, ethyl ester → Pyrrolidin-1-ylacetic acid

Participants

Reaction Steps

The solution of ethyl 2-(pyrrolidin-1-yl)acetate (1.8 g, 11.95 mmol, 1.0 eq) in 8 N HCl was stirred at 95° C. for 16 h. The mixture was concentrated on vacuum pump and quenched and extracted as in Intermediate Example 15(b). The solvent was distilled off to afford the product in 54% yield (1.4 g). LC-MS (ESI): Calculated mass: 129.1; Observed mass 130.1 [M+H]+ (rt: 0.26 min).
