Reaction Steps
Carrying out a reaction as described in Example 1, Step C, except that the 5,6-dichloro-9a-ethyl-7-methoxy-1,2,9,9a-tetrahydro-3H-fluoren-3-one is replaced by an equimolar quantity of [(5,6-dichloro-9a-ethyl-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]acetic acid (Example 20, Step D), there is obtained 5,6-dichloro-9a-ethyl-7-hydroxy-1,2,9,9a-tetrahydro-3H-fluoren-3-one.
