Procedure

To a mixture of 3-ethoxy-4-trifluoromethyl-benzoic acid from step 6 (13.76 g, 59 mmol), N,O-dimethylhydroxylamine hydrochloride (9.17 g, 94 mmol), N-methylmorpholine (9.51 mL, 94 mmol) and 4-DMAP (718 mg, 6 mmol) in DCM (185 mL) and DMF (38 mL) at 0° C. was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC) (13.52 g, 70 mmol), and the mixture was stirred at 23° C. for 18 h. Poured onto ice cold 1 N HCl, extracted with TBME, washed with sat. NaHCO3-sol. and brine, dried over Na2SO4. Removal of the solvent in vacuum left the title compound as a light brown oil (16.15 g, 100%, which was used without further purification. MS (ISP) 278.4 [M+H].
