Reaction Steps

To a solution of N-methoxy-N-methyl-3-(2,2,2-trifluoro-ethoxy)-4-trifluoromethyl-benzamide from step 7 (10.467 g, 32 mmol) in THF (100 mL) at −5° C. was added methylmagnesium bromide (3 M in Et2O, 21.1 mL, 64 mmol). The mixture was stirred at 0° C. for 15 min, then warmed up to 23° C., stirring was continued for further 1.5 h at 23° C. Cooled to 0° C., 1 N HCl (150 mL) was added drop wise, stirring was continued at 23° C. for 15 min, the mixture was diluted with TBME, the phases were separated, the organic layer was washed with water and brine, dried over MgSO4. Removal of the solvent in vacuum left a yellow solid (9.021 g, 100%), which was used without further purification. MS (EI) 286.1 [M].
