Procedure

To a stirred solution of ethyl 2-(3-isopentyl-4-oxo-2-phenylthiazolidin-5-yl)acetate (84 mg, 0.25 mmol) in THF at 0° C. was added LiHMDS (0.28 ml of 1 N, 0.28 mmol) dropwise and the reaction mixture was stirred from 0° C. to RT over 16 hours. The reaction mixture was poured in to 1 N HCl and extracted with EtOAc (4×). The organics were combined, dried (MgSO4) and evaporated to dryness. Purification by preparative TLC (7:1; Hx:EtOAc) gave the desired product as an oil (12 mg).
