Reaction Steps
2,3-Dichloro-4-(2-benzylidenebutyryl)anisole (111.0 g., 0.331 mole) and trifluoroacetic acid (350 ml.) are heated at gentle reflux for 70 hours. The trifluoroacetic acid is removed, the oily residue triturated with ether to give 88.1 g. (80%) of 2-ethyl-3-phenyl-6,7-dichloro-5-methoxy-1-indanone which on crystallization from benzene melts at 141°-143° C.
