Reaction Steps

To an argon purged round bottom flask fitted with a magnetic stirbar was added (S)-2-(1-(benzyloxycarbonyl)pyrrolidin-2-yl)acetic acid (235 mg, 0.893 mmol) followed by anhydrous dichloromethane (5 mL). The reaction was treated with anhydrous DMF (2 drops ˜5 μL). The flow of argon was stopped, and the reaction vessel fitted with a balloon. Oxalyl chloride (0.12 mL, 1.38 mmol) was added in two portions, resulting in effervescence. The reaction was stirred at room temperature for 3 hours, before being concentrated to dryness under reduced pressure and dried overnight under high vacuum.
