反応手順

A mixture of 9.0 g of 19A, 6.8 g of THPA and 100 mL of glacial acetic acid was heated at reflux temperature for 4 hours. The resulting mixture was cooled to room temperature, poured into 450 mL of water and extracted with ether. The extract phase was washed with water, dried (Na2SO4), and filtered, and the solvent was evaporated from the filtrate. The residue was flash-chromatographed on silica gel, with a 15:85 v:v mixture of ethyl acetate and hexane as eluent, to give N-(3-(allyloxy)-4-chloro-6-fluorophenyl)-3,4,5,6-tetrahydrophthalimide (19B), as an orange oil.
