Reaction Steps

8-Bromo-N-(2-chloro-5-(2-hydroxyethylcarbamoyl)phenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide (0.5 g, 0.933 mmol) was dissolved in 5 mL of pyridine. The mixture was stirred at 0° C. and acetic anhydride (0.2 g, 2 eq) was added dropwise. It was stirred at room temperature for overnight. The mixture was poured into ice water and the mixture was extracted by DCM. The combined organics were dried and evaporated in vacuum to afford the acetylated product, 2-(3-(8-bromo-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)-4-chlorobenzamido)ethyl acetate (0.45 g, yield: 83%). LC-MS: (ESI, m/z)=577 [M+H]+
