Intermediate 8: Preparation of 5-Cyano-5-(4-methoxy-8-trifluoromethyl- dibenzofuran-l-yl)-2-oxo-cyclohexanecarboxylic acid methyl esterStep-1: Preparation of 3-(2-Bromo-4-trifluoromethyl-phenoxy)-4-methoxy- benzaldehydeTo a stirred solution of Isovanillin (5 gm, 0.0328 moles) and Potassium carbonate (13.6 gm, 0.0985 moles) in dry DMF (20 ml) was added 3-Bromo-4- Fluorobenzotrifluoride (8.065 gm, 0.0331 moles) over a period of 15 min at room temperature under nitrogen atmosphere, and then above reaction mixture was stirred at 14O0C for 5 hrs. After completion of reaction, the reaction mixture was cooled to room temperature and the contents were poured in to water (100 ml) and extracted with ethyl acetate (3XlOOmI). The organic extracts were combined and washed with
