Part B. Preparation of 6-bromonaphthalen-2 -amine.; [00748] A solution of the product Part A (5.07g, 20.19mmol) and triethylamine (4.22mL, 3.07g, 30.3mmol) in dry DMF (155mL) was treated with the diphenylphosphoroyl azide (6.55mL, 8.34g, 30.3mmol) followed by stirring at room temperature for 3h. The solution was then treated with water (2OmL) followed by warming at 1000C for Ih. The solution was cooled and the flask fitted with a short- path distillation head and the DMF removed by distillation under high vacuum. The solid residue was dissolved in EtOAc and washed with saturated sodium bicarbonate solution. Filtered through celite and the filtrate was washed with water (3x) and then with brine. Dried over Na2SC^, filtered and concentrated under vacuum to give the title compound as a beige solid (4.48g, 100 percent).

YieldReaction ConditionsOperation in experiment
94% at 150℃; for 48 h; 6-bromonaphthalen-2-amine (15)6-Bromonaphthalen-2-ol (1.5 g, 6.7 mmol) was heated with ammonium hydroxide (10ml) and ammonium sulfite (3.5 g, 26 mmol) in a seal tube at 150 0C for 48 h. After cooling to room temperature, ethyl acetate was added and organic layer was separated, washed with brine, dried over anhydrous sodium sulfate and evaporated to obtain crude product 15 (1.4 g, Y; 94 percent), which was pure enough and can be used directly for next step without further purification. 1H NMR (CDCl3): δ 7.84 (IH, br), 7.56 (IH, d, J= 9.6 Hz), 7.43 (2H, m), 6.95 (2H, m), 3.87 (2H, b).

33% With ammonium bisulfite; ammonia In water at 190℃; for 24 h; Preparation of 6-Bromonaphthalen-2-amine (9)
6-Bromo-2-naphthol (2.0 g, 9 mmol), ammonium sulfite (10.4 g, 90 mmol) and 10 mL of ammonia solution were sealed in a tube.
The reaction mixture was heated at 190° C. for 24 hrs and allowed to cool to room temperature, the reaction mixture was extracted with EtOAc. HCl (10percent) was added to the organic layer to give a precipitate.
After filtration, the solid was dissolved in 10percent of Na2CO3 and extracted with EtOAc, the organic layer was dried over Na2SO4.
The solvent was removed under reduced pressure to give the product as yellow solid (0.67 g, 33percent). MS [M++43]=265, LC-MS: tR=20.14 min.
21% With ammonium hydroxide; ammonium sulfite monohydrate In water at 120℃; for 17 h; General procedure: Ammonium hydroxide aqueous solution ( 841mg, 27.8 mmol, 2 equiv.) was added to a freshly prepared aqueous solution of ammonium sulfite monohydrate (3.2 g, 27.8 mmol, 2 equiv.) in a 35 ml high pressure reaction vessel. Appropriate 2-naphthol analog (1a or 1b) (13.9 mmol, 1 equiv.) was added, and the mixture was stirred for 17 h at 120 °C. The reaction mixture was filtered and the precipitate was washed with cold 5percent aq. NaOH and then dissolved in DCM. The organic layer was again washed with 5percent aq. NaOH (3×30 mL) and dried over anh. sodium sulfate to afford 2-naphthylamines after the removal of solvent in vacuo.
