acetamide (35). Procedure was adapted from previously reported literature. 2-(2fluorophenyl)acetic acid (0.053 g, 0.34 mmol, 1.5 eq) and DIPEA (0.16 mL, 0.91 mmol, 4 eq) were added to a thick-walled 0.5-2 mL Biotage microwave vial equipped with stirbar and the vial was sealed. The vial was then purged and flushed with Argon repeatedly. The vial was placed in a 90°C sandbath and T3P (320 uL 50% w/w in MeCN, 0.48 mmol, 2 eq) was added dropwise to the stirring mixture. This mixture was allowed to stir for 1-2 hours at 90°C. In a separate vial, 5 (0.050 g, 0.23 mmol, 1 eq) was added and then dissolved in 200 uL of HFIP. This solution was then added dropwise to the sealed microwave vial. The vial was then allowed to stir at 90°C overnight.
