Procedure:
3-[6-(2-Fluoro-phenyl)-pyridin-3-yl]-acryloyl chloride hydrochloride salt was prepared in quantitative yield by boiling 3-[6-(2-fluoro-phenyl)-pyridin-3-yl]-acrylic acid in thionyl chloride, followed by removal of the volatiles by coevaporating three times with toluene. 3-[6-(2-Fluoro-phenyl)-pyridin-3-yl]-acryloyl chloride hydrochloride salt was dissolved in pyridine, and 1 equivalent of the respective amine was added. The reaction mixture was stirred at room temperature for 2 h. The solvent was removed under reduced pressure, and residual pyridine was removed by coevaporating three times with toluene. The residue was dissolved in DMF, and the product was purified by preparative RP HPLC eluting with a gradient of 0 to 100% acetonitrile in water (+0.01% TFA). After lyophilization, the product was obtained as a solid.

Procedure:
To the solution of 0.7 gram (2.5 mmoles) of 2-bromo-naphtho[2,3-b]furan-4,9-dione in 20 mL of tetrahydrofuran at room temperature, 0.4 grams (5.0 mmoles) of MeSNa in 5 mL of water was added dropwise over 1 minute. The mixture was further stirred for 2 hours at room temperature, and then evaporated to remove tetrahydrofuran. To the residue, 20 mL of 1 N hydrochloric acid was added, and the resulting mixture was filtered. The solid was washed with water, and then crystallized in ethanol/water. Pure crystal product was filtered and dried under vacuum. 0.55 grams of product (yield 90%) was obtained and characterized by 1H NMR and mass spectrum. 1H NMR (in CDCl3) δ 2.66 (s, 3H), 6.79 (s, 1H), 7.75-7.79 (m, 2H), 8.18-8.25 (m, 2H).

Procedure:
To a solution of 4-bromoaniline (8.6 g, 50 mmol) in MeOH (100 mL) was added ethyl glyoxalate (12 mL, 60 mmol, 50% in toluene) and the resulting mixture heated at reflux for 3.5 h.

The resulting mixture was heated at 65° C. for 4 h, then cooled to rt and poured to water (500 mL) and the resulting solid collected by filtration. The crude material thus isolated was crystallized from ethyl acetate/hexane to give pure 3-(4-bromophenyl)-3H-imidazole-4-carboxylic acid ethyl ester (4).
