The synthetic route is as follows., Quality Control of 3-Chloro-5-fluorobenzonitrile

Step 3: 3-Chloro-5-{[5-chloro-l-(4-methoxybenzyl)-lH-l,2,3-benzotriazol-4- yl]oxy}benzonitrile; A stirred suspension of 5 -chloro-l-(4-methoxybenzy I)- IH- 1,2, 3 -benzotriazol-4-ol (0.050 g, 0.173 mmol), 3-fluoro-5-chloro-benzonitrile (0.081 g, 0.518 mmol) and cesium carbonate (0.068 g, 0.207 mmol) in NMP (1.5 mL) was heated at 1400C for 72 hours. The reaction mixture was then quenched with aqueous ammonium chloride (25 mL) and extracted with dichloromethane (2 x 100 mL). The combined extracts were concentrated under reduced pressure. The resulting residue was subjected to reverse phase chromatography (5-95% MeCN/H2theta, 0.1% TFA). The product fractions were combined and extracted with dichloromethane (2 x 100 mL). The combined extracts were dried over MgSO4, filtered and concentrated under reduced pressure to yield the title product. lH NMR (DMSO dbeta) delta 7.90- 7.88(m, IH), 7.80(s, IH), 7.79-7.75(m, IH), 7.60-7.55(m, 2H), 7.40-7.35(d, J-6.9Hz, 2H), 6.95- 6.88 (m, 2H), 5.80(s, 2H), 3.71(s, 3H).
