Procedure

The product from Example 168a (2.0 g. 6.8 mmol) was treated with oxalyl chloride (9.0 g, 13.6 mmol) and catalytic DMF at 60° C. for 5 h. The excess oxalyl chloride was removed under vacuum. The residue was chased with benzene to give the desired product (2.2 g, 94%).

Workup

  1. customThe excess oxalyl chloride was removed under vacuum
