Iodoethane (46 mL, 575.03 mmol) was added and the mixture was stirred for 16 hours at 35° C. Further iodoethane (46 mL, 575.03 mmol) and 1,8-diazabicyclo[5.4.0]undec-7-ene (76 mL, 511.14 mmol) were added and stirring was continued for 24 hours at 35° C.

The filtrate was extracted with DCM and the organic solution was dried with magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by flash column chromatography on silica using gradient elution (30% MTBE/heptane to 100% MTBE). A second crop of the desired product (12 g, 24.12 mmol, 7.55%), was thus isolated as a yellow solid which was later combined with the first crop: 1H NMR Spectrum: (DMSO-d6) 1.41 (9H, s), 1.44 (9H, s), 1.48 (3H, t), 1.52-1.69 (2H, m), 1.87-2.04 (2H, m), 2.79-3.03 (3H, m), 3.86-4.03 (2H, m), 4.59 (2H, q), 7.89 (2H, s), 8.85 (1H, s); Mass Spectrum [M+H]+=498.

Upon the completion of the addition, the resulting mixture was heated to reflux for 1.5 hours and cooled until precipitate was formed. The solid was filtered, washed with water (50 ml×3) and dried in vacuo to give N-(5-fluoro-2-oxo-2,3-dihydro-1H-indol-6-yl)-acetamide (1.25 g, 99%) as a white solid.

Procedure:
To a suspension of (2S)-2-aminobutanoic acid (10 g) and activated carbon (116 mg) in tetrahydrofuran (50 mL) was added dropwise a solution of triphosgene (10.07 g) in tetrahydrofuran (50 mL) at room temperature, and the mixture was stirred at 50° C. for 2 hr. The same experimental process was performed twice, in each of which insoluble materials were filtered off with celite, and the filtrates were combined and concentrated under reduced pressure. The residue was washed with hexane to give the title compound as a solid (yield: 22.39 g, 89%).

Procedure:
4,6-dichloropyrimidine (6.0 g, 40 mmol) and 2-methoxyphenylboronic acid (4.41 g, 29 mmol) were added to a solution of dimethoxyethane (120 mL) and water (18 mL), followed by the addition of NaHCO3 (6.72 g, 80 mmol) and (PPh3)2PdCl2 (0.84 g). to this end the reaction mixture was allowed to reflux for 8 h, and then the solvent removed under reduced pressure.

Procedure:
To a microwave vial were added (S)-5,5-dimethyl-4-phenyloxazolidin-2-one (1 g, 5.23 mmol), 2-chloro-4-iodopyridine (1.878 g, 7.84 mmol) (commercially available from Frontier Scientific, Inc., Logan Utah), and dioxane (10.46 mL). Tribasic potassium phosphate (5.55 g, 26.1 mmol) and copper (I) iodide (0.996 g, 5.23 mmol, commercially available from Sigma-Aldrich, Milwaukee, Wis.) were then added to the vial. The vessel was purged with argon and then N,N′-dimethylethylenediamine (1.126 mL, 10.46 mmol, commercially available from Sigma-Aldrich, Milwaukee, Wis.) was added. The vessel was then irradiated at 140° C. for 40 minutes, and LC-MS indicated complete conversion to the desired product. After cooling to room temperature, the reaction mixture was passed through a syringe filtered, and the material thus obtained was absorbed onto a plug of silica gel and purified by chromatography through a Redi-Sep pre-packed silica gel column (40 g), eluting with a gradient of 0% to 10% MeOH in DCM, to provide (S)-3-(2-chloropyridin-4-yl)-5,5-dimethyl-4-phenyloxazolidin-2-one. m/z (ESI) 303.3 (M+H)+.
