Reaction Steps
To a solution of the product from Example 11B (0.211 g, 0.538 mmol) in dichloromethane (1.35 mL) at 0° C. were added DMF (4 μL) and a solution of oxalyl chloride in dichloromethane (2M, 0.538 mL) and the mixture was stirred for 45 minutes at 0° C. The solvent was evaporated under reduced pressure and the residue was used without further purification.
