YieldReaction ConditionsOperation in experiment
72% In tetrahydrofuran; for 0.5h; 35A. Ethyl [(3-chloro-2,6-difluorophenyl)carbamoyl]formate: To a solution of <strong>[287172-82-1]3-chloro-2,6-difluoroaniline</strong> (430 mg, 2.55 mmol) and TEA (0.5 mL, 3.59 mmol) in THF (5 mL) was added ethyl 2-chloro-2-oxoacetate (0.3 mL, 2.63 mmol). A white precipitate was formed immediately. After 30 min, the reaction mixture was filtered and rinsed with ether. The filtrate was concentrated to yield a crude yellow oil, which was purified by silica gel chromatography to yield the desired product (484 mg, 72%) as a white solid. 1H NMR (500 MHz, CDC13) δ 8.42 (br. s., 1H), 7.35 (m, 1H), 6.98 (m, 1H), 4.45 (q, J = 7.2 Hz, 2H), 1.45 (t, J = 7.2 Hz, 3H). MS (ESI) m/z: 263.9 (M+H)+.

YieldReaction ConditionsOperation in experiment
15% With acetic acid; In ethanol; at 70℃; for 92.0h;Sealed tube; [00395] Intermediate 35A. Ethyl 3-((3-chloro-2,6-difluorophenyl)amino)-2- nitroacrylate: A sealed, high pressure vial containing a clear, colorless solution of ethyl nitroacetate (0.170 ml, 1.529 mmol), triethylorthoformate (0.255 ml, 1.529 mmol), 3- chloro-2,6-difluoroaniline (0.250 g, 1.529 mmol), acetic acid (0.026 ml, 0.459 mmol), and EtOH (1.529 ml) was heated to 70 C. After 92 h, the clear, dark yellow solution was concentrated to give an orange oil. Purification by normal phase chromatography gave Intermediate 35A (0.0721 g, 15%) as a yellow solid. MS(ESI) m/z: 307.0 (M+H)+.

YieldReaction ConditionsOperation in experiment
56% [00377] Intermediate 26A. 2-Azido-4-chloro-l,3-difluorobenzene: To a solution of 3- chloro-2,6-difluoroaniline (1.7 g, 10.39 mmol) in TFA (10 mL) and water (2 mL) at 0 C was added sodium nitrite (0.717 g, 10.39 mmol) over a period of 0.5 h. After completion of addition, sodium azide (1.716 g, 26.4 mmol) in water (5 mL) was added dropwise. The reaction mixture was stirred at 0 C for 10 min and then allowed to warm to rt. The reaction was diluted with water (75 mL) and extracted with EtOAc. The organic layer was dried and concentrated to give the desired product (1.16 g, 56%) as a brown solid.

YieldReaction ConditionsOperation in experiment
With sulfuric acid; at 120℃; for 2.0h;Inert atmosphere; General procedure: To a solution of 3-(trifluoromethyl)aniline(5.0 g, 31 mmol) and trimethyl orthoformate (4.9 g, 46.5mmol) was added three drops of sulfuric acid.This mixture was slowly heated to 120 oC to allow MeOH to be distilled off, stirred for 2 h at 120 oC, heated to 170 oCfor 30 min, and cooled to 100 oC.Then aq. HCl (10%; 25 mL) was added.This mixture was then refluxed for 3 h, cooled to 0 oC (ice bath) and finally basified with aq. NaOH (20%).This solution was extracted with EtOAc (3 × 30 mL), dried (MgSO4), filtered, and concentrated under reduced pressure. The crudeproduct was purified on a silica gel column with gradient elution (hexanes hexane-EtOAc; 1: 10 v/v) to afford S7 as a colorless oil
