Procedure:
1.6 g of 1,3-dimethyl-6-{2-[N-(2-hydroxyethyl)-3-(4-nitrophenyl)propylamino]ethylamino}-2,4(1H,3H)-pyrimidinedione (Compound d) and 0.8 g of acetic anhydride were dissolved in 5 ml of pyridine.

Procedure:
2-Bromo-4-fluoro-aniline (13.8 g, 72.6 mmol) was added dropwise to a solution of boron trichloride in methylene chloride (1.0 M, 81.1 mL, 81.1 mmol) cooled with ice water. The reaction mixture was warmed to room temperature, stirred for 30 min, and chloroacetonitrile (13.5 mL, 87.1 mmol) and aluminum chloride (13.5 g, 98.4 mmol) added, followed by 1,2-dichloroethane (95 mL). The reaction mixture was heated to 70° C. to distill off methylene chloride, and then refluxed for 24 h. After cooling to 0–5° C., the mixture was treated with 2.5 M HCl (130 mL) carefully, and then heated to 80° C. for 1 h until all solids dissolved. The aqueous layer was separated and extracted with methylene chloride. The combined organic solutions were washed with water and brine, dried (sodium sulfate) and concentrated to a yellow solid (11, 56.9%), which was used without further purification. The crude product was taken into dioxane (68 mL) and water (7.6 mL), and treated with sodium borohydride (1.64 g) in portions. After 30 min at room temperature, all the starting material was consumed, and the reaction mixture was heated to reflux for 18 h. The mixture was cooled to room temperature, treated with 0.1 N HCl (70 mL), 2N HCl (20 mL) and concentrated HCl (15 mL), and extracted with ethyl acetate. The organic layer was separated and washed with water and brine, dried (sodium sulfate), and concentrated. Column chromatography on silica gel (hexanes/ethyl acetate) gave 5-fluoro-7-bromoindole (4.4 g, 52.2%). 1H NMR (400 MHz, CDCl3) 6.49, (dd, J1=2.35 Hz, J2=3.13 Hz, 1H), 7.06 (d, J1=2.35 Hz, J2=8.60 Hz, 1H), 7.14˜7.17 (m, 2H), 8.18 (br, 1H); MS (ES, m/z): C8H5BrFN: 211.9 (M+(79Br)−1), 214.0 (M+(81Br)−1).

Procedure:
To a solution of tert-butyl (3S)-3-({[(5-amino-1-methyl-1H-pyrazol-4-yl)amino]carbonyl}amino)-1-pyrrolidinecarboxylate (1.8 g) and N-ethyldiisopropylamine (720 mg) in chloroform (50 ml) was added trityl chloride (1.6 g), and the mixture was stirred at room temperature for 28 hours. The reaction mixture was washed successively with 10% aqueous citric acid solution, brine and saturated aqueous sodium hydrogen carbonate solution. The organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with 3% methanol/chloroform to give tert-butyl (3S)-3-[({[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]amino}carbonyl)amino]-1-pyrrolidinecarboxylate (1.7 g) as a solid.

Procedure:
A microwave vial was charged with INTERMEDIATE D (0.100 g, 0.192 mmol), (N-tert-butoxycarbonyl)-1,2,3,6-tetrahydropyridine-4-boronic acid pinacol ester (Maybridge Chemicals, Cornwall, UK, 0.059 mL, 0.192 mmol), tetrakis(triphenylphosphine)palladium(0) (0.022 g, 0.019 mmol), and K2CO3 (0.133 g, 0.959 mmol). The solids were diluted with dioxane (1.279 mL) and water (0.639 mL), and the reaction was heated under microwave irradiation at 100° C. for 10 minutes (starting material remained, but moved forward). The reaction mixture was diluted with water, and washed with DCM. Equal partitioning between both layers was observed (and an emulsion formed), so the organic and aqueous were combined and concentrated until just the water remained. The aqueous was washed with DCM (×3) and the organics were then combined and dried using a phase separator. After concentration, the material was purified by reverse-phase preparative HPLC (Column: Phenomenex 150×30 mm, 5 micron, C18 column; 0.1% TFA in CH3CN/H2O, gradient 25% to 90% over 20 min) to provide tert-butyl 4-(2-(7-(N-(1,2,4-thiadiazol-5-yl)sulfamoyl)-2H-benzo[b][1,4]oxazin-4(3 H)-yl)-5-(trifluoromethyl)phenyl)-5,6-dihydropyridine-1(2 H)-carboxylate (0.035 g, 0.056 mmol) as a light-yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.37 (s, 9 H) 2.16-2.37 (m, 2 H) 3.51-3.72 (m, 4 H) 3.81-3.90 (m, 2 H) 4.22-4.34 (m, 2 H) 5.84 (br. s., 1 H) 6.38-6.46 (m, 1 H) 7.10-7.17 (m, 2 H) 7.56 (d, J=8.31 Hz, 1 H) 7.65 (d, J=2.05 Hz, 1 H) 7.72 (dd, J=8.41, 2.15 Hz, 1 H) 8.42 (s, 1 H). m/z (ESI) 524.0 (Boc group falls off in LCMS).

Procedure:
A solution of 4-(4′-dibenzofuran-4-yl-bipheny-4-yloxy)-N-tert-butoxycarbonyl-proline methyl ester (400 mg, 0.71 mmol) in THF (3 mL) and methanol (4 mL) was cooled to 0° C. and treated with 2 N KOH (1.25 mL). After stirring at room temperature for 1 H the solution was acidified with 10% HCl to pH 2 and diluted with 25ml of ethyl acetate. After being separated, the aqueous layer was extracted with ethyl acetate (3×15 mL) and the combined organic layers were dried over MgSO4 and concentrated. Purification by flash column chromatography (2-5% methanol in dichloromethane) provided 4-(4′-dibenzofuran-4-yl-bipheny-4-yloxy)-N-butoxycarbonyl-proline (320 mg, 82%) as pale yellow solid. 0.320 g (yield 82.1%). 1H NMR (DMSO-d6), δ 8.16 (dd, J=8, 12 Hz, 2H), 7.98 (d, J=9 Hz, 2H), 7.80 (m, 6H), 7.47 (m, 3H), 6.97 (d, J=9 Hz, 2H), 5.08 (m, 1H), 4.29 (t, J=9 Hz, 1H), 3.72 (m, 1H), 3.42 (dd, J=6, 9 Hz, 1H), 2.62 (m, 1H), 2.20 (m, 1H), 1.44 (s, 9H).
