Reaction Steps
3-Chloro-N-(2-fluoro-4-hydroxyphenyl)propanamide (2.1 g) was mixed with anhydrous AlCl3 (7 g) and heated at 160° C. overnight. The resultant mixture was treated with 1N HCl and extracted with EtOAc. After isolation of the organic layer and removal of solvents under reduced pressure, the desired crude product (1.8 g) was collected as light brown solids.
