Procedure

To a solution alcohol (300 mg) from Step 4 in Ac2O (2 mL) was added pyridine (300 mL) and DMAP (2 mg). After 2 hr, the reaction mixture was diluted with Et2O, washed with H2O, a solution of CuSO4, and the solvent evaporated to give the title product which was used as such for the next step.

Workup

  1. washwashed with H2O
  2. customa solution of CuSO4, and the solvent evaporated
