An azeotrope of t-butanol and toluene (85 ml) is collected at temperatures of 120° C. to 135° C. and is discarded. The mixture is cooled to ambient temperature, and a solution of 14.59 g (80.6 mmol) of methyl 4-nitrobenzoate in 30 ml of N,N-dimethylformamide is added over a period of 15 minutes with cooling in a water bath. The mixture is heated at 100° C. for 14 hours, cooled to 20° C., and quenched with 1500 ml of ice water. The precipitate is filtered, dried in air and dissolved in 500 ml of acetone. The solution is filtered to remove insolubles, and the filtrate is concentrated by evaporation and cooled to precipitate methyl 4-(4-phenoxyphenoxy)benzoate. The recovered product weighs 21.23 g (82 percent yield) and has a melting point of 114° C. as determined by DSC.

Procedure:
307 ml (615 mmol) of an aqueous potassium carbonate solution (2M) are added dropwise to a mixture of 61.5 g (205 mmol) of tert-butyl (3-bromobenzyl)-N-methylcarbamate, 46 g (307 mmol) of 4-formylbenzeneboronic acid and 500 ml of toluene. The reaction medium is subsequently degassed with argon and 7 g (6.2 mmol) of tetrakis(triphenylphosphine)palladium(0) are added. After heating at 90° C. for 24 hours, the reaction medium is poured into water and extracted with ethyl acetate. The organic phase is separated by settling, dried over magnesium sulfate and evaporated. The residue obtained is purified by chromatography on a silica column eluted with a mixture of heptane and ethyl acetate (70/30). After evaporating the solvents, 67 g of tert-butyl (4′-formylbiphenyl-3-yl)methylcarbamate are collected. Yield=60%.

Procedure:
Upon stirring a mixture of florfenicol (8.8 g, 1 equivalent), diisopropylethylamine (5 mL, 1.2 equivalents), and 4-N,N-dimethylaminopyridine (1.2 g, 0.4 equivalent) in tetrahydrofuran (90 mL) at −20° C., a solution of 4-bromobutyryl chloride (5 g, 1.1 equivalent) in tetrahydrofuran (15 mL) was added via a syringe. The solution was stirred at room temperature under a nitrogen atmosphere overnight and diluted with ethyl acetate. The resulting solution was washed with 1 M HCl(aq) and the organic layer was separated and concentrated to give a brown oil. The crude oil was purified by gel column chromatography to give 4-bromo-butyric acid 2-(2,2-dichloro-acetyl amino)-3-fluoro-1-(4-methanesulfonyl-phenyl)-propyl ester (5.6 g, 45% yield) as a brown foam; H1-NMR (DMSO-d6), δ=2.1 ppm (p, 2H), 2.6 ppm (t, 2H), 3.2 ppm (s, 3H), 3.5 ppm (t, 2H), 4.2-4.6 (m, 3H), 6.0 ppm (d, 1H), 6.4 ppm (s, 1H), 7.6 ppm (d, 2H), 7.9 ppm (d, 2H), 8.9 ppm (d, 2H).

Procedure:
To a solution of tert-butyl 3,6-dihydropyridine-1(2H)-carboxylate (617 g, 3.37 mol) in anhydrous DCM (10 L) was added m-CPBA (989 g, 5.73 mol) in portions at 0° C. The mixture was stirred at room temperature for 1 hour. Saturated Na2S2O3 (1 L) was added and the organic layer was separated. The organic layer was washed with 5% aqueous K2CO3 (5 L×2), brine (4 L), dried over sodium sulfate, and concentrated under reduced pressure.
