Reaction Steps

0.29 g (3.77 mmol) 1-fluoro-propan-2-ol in 20 mL THF is cooled down to 0° C. 4.90 mL (1 M in THF; 4.90 mmol) LiHMDS is added drop wise. After 60 minutes of stirring at 0° C. 0.60 g (3.77 mmol) 2,4-difluoro-1-nitro-benzene is added. The mixture is stirred for 2 h. The mixture is diluted with water and EtOAc. The organic layer is washed with brine, separated, dried and evaporated giving rise to the crude 4-fluoro-2-(2-fluoro-1-methyl-ethoxy)-1-nitro-benzene. 80.0 mg palladium on charcoal (10%) and MeOH are added hydrogenated in a Parr apparatus (RT; 50 psi; 5 h). The catalyst is filtered off and the solvent is evaporated.
