Procedure

2-Ethyl-2-n-propyl-5-methoxy-6,7-dichloro-1-indanone is prepared following substantially the same procedure described in Example 5, Step E, using the following substances: 2-ethyl-5-methoxy-6,7-dichloro-1-indanone (13 g., 0.05 mole), sodium hydride (1.3 g., 0.055 mole), 1,2-dimethoxyethane (500 ml.) and n-propyliodide (6 ml.). The above procedure gives 6.0 g. of 2-ethyl-2-n-propyl-5-methoxy-6,7-dichloro-1-indanone which after recrystallization from ethanol melts at 92° C.
