Product 1

HCID 137534392(s)-(Acetoxyacetyl)-pyrrolidine trifluoroacetic acid salt

Procedure

A solution of 1.00 g of the product of Example 2 can be kept in 10 ml of 1:1 trifluoracetic acid-acetic acid at 20° for 30 minutes. The solvents can then be removed under reduced pressure to give (S)-2-(2-acetoxy-1-oxoethyl)-pyrrolidine trifluoracetate.

Workup

  1. customThe solvents can then be removed under reduced pressure
