Reaction Steps
Carrying out a reaction as described in Example 1, Step D, except that the 5,6-dichloro-9a-ethyl-7-hydroxy-1,2,9,9a-tetrahydro-3H-fluoren-3-one and ethyl bromoacetate are replaced by equimolar quantities of 5,6-dichloro-7-hydroxy-9a-methyl-1,2,9,9a-tetrahydro-3H-fluoren-3-one and ethyl 1-bromocyclopentane-1-carboxylate, there is obtained ethyl 1-[(5,6-dichloro-9a-methyl-3-oxo-1,2,9,9a-tetrahydro-3H-fluoren-7-yl)oxy]cyclopentane-1-carboxylate.
