53% To a solution of 2-amino-3-fluorobenzonitrile (17.07 g, 0.125 mol) in 1,4-dioxane (20 ml) was added 48% aqueous hydrobromic acid (200 ml) and the solution was cooled to 0C before adding dropwise a solution of sodium nitrite (9.95 g, 0.144 mol) in water (22 ml) over 35 min so that the temperature did not rise above 3C. The resulting mixture was stirred at 2-3C for 2 h then poured onto a cooled (5C) solution of copper (I) bromide (26.98 g, 0.188 mol) in 48% hydrobromic acid (100 ml). The mixture was stirred for 10 min then heated to 50C over 1 h. The mixture was cooled to ambient temperature, diluted with water (11) and extracted with diethyl ether (2 x 500 ml). The combined organic extracts were washed with 1 M aqueous Na2SO3 (500 ml), then saturated aqueous NH4C1 (200 ml), dried (MgSO4), and evaporated to give a brown oil/solid. Purification by chromatography (silica gel, 10% EtOAc/isohexane) and trituration of a mixed fraction with isohexane afforded 13.22 g (53%) of 2-bromo-3- fluorobenzonitrile as a pale yellow solid : 1H NMR (360 MHz, CDCl3) 5 7.62-7. 68 (1H, m), 7.74-7. 85 (1H, ddd, J 9, 9,1), 7.74-7. 85 (1H, ddd, J 8, 1, 1).
2-Amino-3-fluorobenzonitrile (9.8 g, 71.9 mmol) was bromo-deaminated as described in Example 1 to afford 2-bromo-3-fluorobenzonitrile as a pale brown solid: 1H NMR (360 MHz, CDCl3) delta 7.62-7.68 (1H, m), 7.74-7.85 (1H, ddd, J 9, 9, 1 Hz), 7.74-7.85 (1H, ddd, J 8, 1, 1 Hz).

Bis(triphenylphosphine)palladium(II)- dichloride (270 mg, 0.38 mmol) was added and the mixture was heated at 120 C overnight. The mixture was diluted with EtOAc (200 mL) and the solution was washed with water (2 x 30 mL) and brine, then dried (Na S04). After concentrating to dryness the material was dissolved in MeOH (30 mL) and concentrated to dryness again. The concentration step from MeOH was repeated a total of five times until about 2.1 g of a tan colored solid was obtained. This intermediate (2.1 g) was stirred in THF (20 mL) and water (10 mL) and was treated with 3-fluoro-2-bromo-l-cyanobenzene (1.2 g, 6 mmol) and K2C03 (1.5 g, 10.8 mmol). The mixture was purged with nitrogen for five minutes, then bis(di-t-butylphosphine) ferrocene palladium(II)dichloride (130 mg, 0.2 mmol) was added. The solution was heated at 60 C overnight. The cooled mixture was diluted with EtOAc (120 mL) and washed with water (30 mL). The organic phase was dried (Na2S04) and concentrated. The crude product was purified on an Analogix automated chromatography system eluting with 0-3% MeOH/CH2Cl2. The partially purified mixture was further purified on a reverse-phase CI 8 column eluting with 0-50% acetonitrile/water. The purest fractions were collected and concentrated to remove acetonitrile and the solid was isolated by filtration. This solid was passed through a short silica gel column eluting with 3% MeOH/CH2Cl2 to give 320 mg (17%) of 108 with 99.8% purity. 1H-NMR (300 MHz, CDC13): delta 1.89 (s, 1H), 7.42-7.44 (m, 0.19H), 7.45-7.47 (m, 0.65H), 7.47-7.50 (m, 0.76H), 7.51 (app d, J= 1.46, 0.33H), 7.53-7.67 (m, 6H), 7.99 (dd, J= 0.7, 1.7, 1H), 8.12 (s, 1H). 13C-NMR (75 MHz, CDC13): delta 109.95, 116.31, 117.79, 118.11, 120.75, 121.05, 121.32, 127.03, 127.15, 127.38, 129.32, 129.37, 131.15, 131.27, 132.53, 142.47, 143.92, 144.65, 158.05, 161.41.
