Procedure

A solution of the product of Example 6A (198 mg, 0.8 mmol) in dichloromethane (10 mL) was stirred with oxalyl dichloride (Aldrich, 2.0 mmol) and 1 drop of dimethylformamide at ambient temperature for 2 hours. The title compound was obtained by removing the solvent under vacuum as a yellow oil (250 mg) and the compound was used directly in the next step.
