Reaction Steps

To a solution of chloroacetic acid (0.715 g, 7.56 mmol, 1 eq.) in DCM (15 mL) and THF (12 mL) at r.t. was added EDC.HCl (1.89 g, 9.83 mmol, 1.3 eq.) and HOBt (1.33 g, 9.83 mmol, 1.3 eq.). The reaction mixture was stirred at r.t. for 30 min and then 3-acetamidopyrrolidine (1.26 g, 9.83 mmol, 1.3 eq.) was added. After stirring two days at r.t., the reaction mixture was diluted with water, HCl 1 M, and DCM. The aqueous phase was extracted with DCM five times. The combined organic layers were washed with a saturated NaHCO3 solution, with brine, dried over Na2SO4, filtered and concentrated in vacuo. The resulting crude oil was used as such in the next step.
