Reaction Steps

To a pre-cooled solution of acid 214 (1.25 g, 3.02 mmol, scheme 52) in THF (12.07 mL) was added DMF (0.023 mL, 0.302 mmol) and oxalyl chloride (0.660 mL, 7.54 mmol) and the resultant solution was stirred at 0° C. for 30 min. The solvent was evaporated, the residue was triturated with ether and dried under high vacuum to give title compound 219 (1.306 g, 3.02 mmol, 100% yield) as a beige solid. MS: 429.2 (MH+, COOMe), 433.1 (COCl, MH+).
