Participants

Reaction Steps

2-Ethyl-2-n-propyl-5-hydroxy-6,7-dichloro-1-indanone is prepared following substantially the same procedure described in Example 5, Step F, using the following substances: 2-ethyl-2-n-propyl-5methoxy-6,7-dichloro-1-indanone (11 g., .037 mole), aluminum chloride (12.5 g., 0.094 mole) and heptane (400 ml.). The above procedure gives 9.0 g. of 2-ethyl-2-n-propyl-5-hydroxy-6,7-dichloro-1-indanone which after recrystallization from methylcyclohexane melts at 153° C.
