EXAMPLE 72; Preparation of 4-fluoro-5-methoxy-2-nitroaniline; [0148] To an ice cooled 100 ml round bottom flask charged with 30 ml of methanol was added 0.40 g (17.4 mmol) of sodium. After the solution was homogeneous, Ig (5.71 mmol) of 4,5 difluoro, 2-nitro aniline was added. The solution turns a bright yellow and a precipitate slowly forms. After 1 hour the solution was concentrated and 2N HCl added to the residue. The mixture was extracted with ethyl acetate (3 X 30 ml) and the organic layers combined, dried (MgStheta4) and concentrated to yield a yellow solid.IH NMR (CDCl3): delta 7.83 (d,lH, ArH), 6.20 (d,lH,ArH), 6.18 (bs, 2H, NH2), 3.92(s,3H,CH3);MS (ESI) m/z 185 ([M-H]-);Anal, calcd for C7H7FN2O3: C:45.17 H:3.79 N:15.05 Found: C:45.77 H:3.92 N:14.05.

YieldReaction ConditionsOperation in experiment
With hydrogenchloride; sodium methylate In methanol 1 Step 1: Step 1: Preparation of 4-fluoro-5-methoxy-2-nitroaniline To an ice cooled 100 ml round bottom flask charged with methanol (30 mL) was added sodium methoxide (1.551 g, 28.7 mmol). After the solution was homogeneous, 4,5-difluoro-2-nitroaniline (2 g, 11.49 mmol) was added portion wise. The solution turns a bright yellow and slowly yellow precipitation was observed. Solvent was removed under reduced pressure and the residue was diluted with water and acidified using 1.5N HCl solution. The aqueous layer was extracted with ethyl acetate twice, the combined organic layer was washed with water, brine solution, dried over anhydrous sodium sulphate and concentrated to dryness to get 4-fluoro-5-methoxy-2-nitroaniline (1.8 g, 9.48 mmol, 82% yield) as pale yellow solid. 1H NMR (400 MHz, CDCl3): δ ppm 7.76 (d, J=12.55 Hz, 1H) 7.54 (br. s., 2H) 6.65 (s, 1H) 3.86 (s, 3H). 19F NMR: δ ppm -147.64 (1F); MS:MS m/z 185.2 (M+-1)

In methanol at 20℃; for 12h; 35.1 Step 1: preparation of 4-fluoro-5-methoxy-2-nitroaniline Step 1: preparation of 4-fluoro-5-methoxy-2-nitroaniline 3.4g 2-amino-4,5-difluoronitrobenzene was added to a 100mL round-bottomed flask, and dissolved by adding 30mL MeOH. 2.16g sodium methoxide was slowly added at room temperature. The mixture was reacted for another 12h at room temperature before the reaction was stopped. The reaction solution was filtered, and the filter cake was washed with 10mL cold MeOH, and dried in vacuum to give the title compound, which was used directly in the next step. LC-MS m/z: [M+H]+ =187.
