Reaction Steps
To a mixture of 1-hydroxy-6-(trifluoroacetamido)indane (4.37 g), triphenylphosphine (7.01 g), methylene chloride (70 ml) and tetrahydrofuran (7 ml), at 0° C., was added carbon tetrabromide (8.87 g) in four portions. After 15 min, the reaction mixture was allowed to warm to room temperature and stirred for 4 h. Ethyl acetate was added and the solution was washed (water, brine), dried (MgSO4) and evaporated. The residue was flashed chromatographed, eluting with methylene chloride, to give 6-(trifluoroacetamido)-3H-indene (3.09 g, 76%) as a colorless solid; mp 131.5°-132.5° C.; MS(CI), m/e=228(M+H).
