反应条件: temp:-20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of compound 126 (schemes 6 or 9) (200 mg, 0.381 mmol) in dry tetrahydrofuran (8 mL) under nitrogen at −20° C. was added 4-nitrophenyl chloroformate (115 mg, 0.572 mmol). The reaction mixture was stirred at −20° C. for 2 h. A solution of 3-(dimethylphosphoryl)aniline 287 (97 mg, 0.57 mmol) and N,N′-diisopropylethylamine (0.200 mL, 1.14 mmol) in a mixture of dry tetrahydrofuran (2 mL) and dry N,N′-dimethylformamide (2 mL) were added at −20° C., the reaction mixture was allowed to warm to room temperature slowly, and the stirring was continued for an additional 16 h. The solvent was removed under reduced pressure; the residue was diluted with ethyl acetate, washed with a saturated aqueous solution of ammonium chloride, dried over anhydrous sodium sulfate and concentrated. Purification via Biotage (linear gradient 0-20%, methanol/dichloromethane; 25M column) afforded compound 288 (230 mg, 0.32 mmol, 84%). MS (m/z): 720.4 (M+H). were added at −20° C. to warm to room temperature slowly the stirring was continued for an additional 16 h The solvent was removed under reduced pressure the residue was diluted with ethyl acetate washed with a saturated aqueous solution of ammonium chloride dried over anhydrous sodium sulfate concentrated Purification via Biotage (linear gradient 0-20%, methanol/dichloromethane; 25M column)

实验步骤: To a solution of compound 286 (1.5 g, 7.5 mmol) in methanol (62 ml) and water (12 ml) under nitrogen at room temperature was added ammonium chloride (0.604 g, 11.3 mmol) and iron (1.68 g, 30.1 mmol). The resulting mixture was heated to reflux for 30 min then filtered through celite. The celite pad was rinsed with methanol. The filtrate and washings were combined and concentrated and the residue was purified via Biotage (linear gradient 0-20%, methanol/dichloromethane; 25M column) to afford compound 287 as a yellow solid (1.27 g, 7.51 mmol, quantitative). MS (m/z): 170.1 (M+H). The resulting mixture was heated to reflux for 30 min then filtered through celite The celite pad was rinsed with methanol concentrated the residue was purified via Biotage (linear gradient 0-20%, methanol/dichloromethane; 25M column)
