Reaction Steps

Step L (7): A solution of LiOH/H2O (2M, 28 mg in 0.50 mL) was added to the diastereomer B, (S)-methyl 2-((S)-3-acetamido-3-sec-butyl-2-oxopyrrolidin-1-yl)pent-4-enoate (122 mg, 0.39 mmol) from Step L (6) in THF (1.0 mL) at RT. The reaction was stirred for 3 days. The mixture was poured into 1N HCl and the aqueous layer was extracted with EtOAC. The combined organic layers were washed with brine, dried over NaSO4 and concentrated in vacuo to give 102 mg of the title compound as white solid. LC-MS (M+H)+=297.01.
