Procedure

A solution of (15.1 mmol) of the product from Step E in 73 mL of dichloromethane is treated with 1.4 mL (17 mmol, 1.1 equivalents) of oxalyl chloride and 0.02 mL (0.3 mmol, 0.02 equivalents) of dimethylformamide at ambient temperature, causing some bubbling, and is stirred overnight. The resulting solution of the title compound is used in step G without isolation.
