Procedure:
An ice-cooled solution of 5-bromo-2-fluorophenol (1.91 g, 10 mmol), (1-methyl-1H-[1,2,3]triazol-4-yl)methanol (1.24 g, 11 mmol) and triphenylphosphine (3.93 g, 15 mmol) in tetrahydrofuran (50 ml) was treated dropwise with diisopropyl azodicarboxylate (3.03 g, 15 mmol) over 10 min. The resulting mixture was stirred to ambient temperature over 12 h and then glacial acetic acid (1 ml) was added. The reaction mixture was concentrated in vacuo then partitioned between ethyl acetate and 0.01N sodium hydroxide solution. The organics were washed with water, brine, dried over anhydrous magnesium sulphate and concentrated to give an oil. This oil was purified by chromatography on silica gel, eluting with isohexane on a gradient of ethyl acetate (20-50%). Product-containing fractions were concentrated and the resulting residue triturated with 10% ether in isohexane to furnish 4-(5-bromo-2-fluorophenoxymethyl)-1-methyl-1H-[1,2,3]triazole as a white solid (1.9 g, 66%): δH (360 MHz, d6-DMSO) 4.06 (3H, s), 5.25 (2H, s), 7.10-7.20 (2H, m), 7.55-7.70 (1H, m), 8.19 (1H, s).

Procedure:
Boc-Lys(Z)-Leu-Leu-OMe (12.0 g, 19.33 mmol) was dissolved in acetone (41.0 g, 52 mL) at 22-23° C. A solution of NaOH (1.94 g, 48.5 mmol) in water (18.0 g) was added over 5 min. After stirring for 40 min., the reaction was quenched with a solution of citric acid (10.2 g, 53.0 mmol) in water (18.0 g). The acetone was removed on a rotary evaporator at 40° C. The remaining mixture was extracted with ethyl acetate (2×65 mL). The EtOAc extract was washed with water (50 g) then with aqueous saturated sodium chloride solution (50 g). The EtOAc extract was dried over anhydrous MgSO4 (10 g). The EtOAc solution was filtered and diluted with DMF (40. g). The ethyl acetate was evaporated at 40° C. under reduced pressure to give the solution of the product in DMF. Weight of solution ˜52 g.

Procedure:
To a solution of 50 g of 5-methylimidazo[1,5-a]pyridine [J. Org. Chem. 40, 1210 (1975)] in 625 ml of tetrahydrofuran precooled to -75° is added under nitrogen atmosphere 175 ml of 2.4N n-butyllithium in hexane while maintaining temperature below -53°. The solution of 5-(lithiomethyl)imidazo[1,5-a]pyridine, is cooled back to -75° and a solution of 121.8 g of 5-bromo-1,1,1-triethoxypentane in 125 ml of tetrahydrofuran is added rapidly at which time the temperature rises to -60°. The reaction mixture is allowed to warm to -4° over a 45 minute period and evaporated practically to dryness. The residue is partitioned between 500 ml of ethyl ether and 240 ml of 3N hydrochloric acid. The ether solution is further extracted twice with 60 ml of 3N hydrochloric acid; the combined aqueous extract is basified with 100 ml of concentrated ammonia hydroxide and reextracted twice with 200 ml of ethyl ether. The ether extract is dried over magnesium sulfate and evaporated to dryness to give an oil which is distilled under high vacuum to give 5-(5-ethoxycarbonylpentyl)-imidazo[1,5-a]pyridine boiling at 180°-5°/0.12 mm Hg.

Procedure:
To a solution of 2-[(4-[4-nitro-3-(trifluoromethyl)phenyl]aminocyclohexyl)oxy]acetic acid (100 mg, 0.28 mmol) in dichloromethane (20 ml) was added 2-(piperazin-1-yl)-6-(trifluoromethyl)quinoline (93.1 mg, 0.33 mmol, 1.2 eq), EDAC.HCl (79 mg, 0.41 mmol, 1.5 eq), HOBt (56 mg, 0.41 mmol, 1.5 eq), Et3N (84 mg, 0.83 mmol, 3 eq). The resulting solution was stirred overnight at room temperature and then quenched by the addition of water (50 ml), extracted with of dichloromethane (3×30 ml) and the organic layers were combined and dried over anhydrous sodium sulfate. The organic solution was filtered and then concentrated under vacuum. The crude material was purified by Pre-TLC using 4% methanol in dichloromethane to elute. Concentration of the product-containing fractions afforded 2-[(4-[[4-nitro-3-(trifluoromethyl)phenyl]amino]cyclohexyl)oxy]-1-[4-[6-(trifluoromethyl)quinolin-2-yl]piperazin-1-yl]ethan-1-one as a yellow solid (77 mg, 45%).
