Procedure

Then, 3-(4-(2-isopropyl-phenylsulfanyl)-3-trifluoromethyl-phenyl)-3-oxo-propionic acid ethyl ester 45 was prepared as follows. To a solution of compound 44 (11.5 g, 34.0 mmol) in THF (150 mL) was added 60% sodium hydride in mineral oil (1.84 g, 40.8 mmol). The mixture was stirred at room temperature for 10 minutes. Diethyl carbonate (46.5 mL, 340 mmol) was added and the mixture was heated under reflux for 2 hours. 10% HCl aq. (100 mL) was added and the solution was extracted with ethyl acetate (200 mL). The organic layer was separated, washed with brine (5×250 mL), dried over MgSO4 and filtered. The filtrate was concentrated on a rotor-vapor to give a brown oil 45 (10.6 g, 76%); MS (DCI) m/z 411 (M+H)+; 428 (M+NH4)+.
