YieldReaction ConditionsOperation in experiment
With potassium carbonate; In N,N-dimethyl-formamide; at 100℃; for 18h; Step A: 1 -fluoro-3 -(3 -(methylsulfonyl)propoxy)-5 -(trifluoromethyl)benzene (10-2)To a solution of compound 10-1 (400 mg, 2.22 mmol) in DMF (5.0 mL) was added compound la (973 mg, 3.33 mmol), and K2C03 (613 mg, 4.44 mmol). The resulting mixture was stirred at 100 C for 18 hours. H20 was added and the resulting mixture was extracted with EtOAc (15 mL x 3). The combined organic layers were washed with brine, dried and concentrated to give a residue, which was purified by preparative TLC on silica gel eluted with petroleum ether:ethylacetate (5:1) to give compound 10-2.

YieldReaction ConditionsOperation in experiment
With potassium carbonate; In N,N-dimethyl-formamide; at 100℃; for 6h; 1 .1 : 1 -fluoro-3-[3-fluoro-5-(trifluoromethyl)phenoxy]-2-nitro-benzene A suspension of 3-fluoro-5-(trifluoromethyl)phenol (1 g, 5.55 mmol), 1 ,3-difluoro-2-nitro- benzene (0.88 g, 5.55 mmol) and K2C03 (1 .53 g, 1 1.1 mmol) in DMF is heated to 100 C for 6 h. Water and ethyl acetate are added and the phases separated. The organic phase is washed with water, dried over anhydrous Na2S04 and concentrated under reduced pressure. Column chromatography (ISCO-Combi Flash Rf, cyclohexane/ethyl acetate) of the crude product yields the desired product in 85% (1.50 g). HPLC: 12 = 1 .433 min;MS (ESI) m/z = 320 [M+H+].
