Procedure

A 3',4'-dihydrospiro[cyclohexane-1,1'(2'H)-naphthalen]-4-one (r) produced in step (10) has its 4-keto function reduced, e.g., by mixing said compound in a solvent such as ethanol with sodium borohydride at moderate (room) temperature for from about 3 to about 8 hours, to produce a corresponding 3',4'-dihydrospiro[cyclohexane-1,1'(2H)naphthalen]-4-ol (s).
