With potassium acetate;tetrakis(triphenylphosphine) palladium(0); In N,N-dimethyl-formamide; at 120℃; for 17h; | 5-Nitro-3-thiazol-5-yIpyridin-2-ol; NO2[787] N2 was bubbled through a solution of <strong>[25391-58-6]3-iodo-5-nitropyridin-2-ol</strong> (1.33g,S.OOmmol), thiazole (2.13g, 25.0mmol), potassium acetate (1.47g, IS.Ommol), andtetrakis(triphenylphosphine)palladium(0) (0.4g, 0.4mmol) in DMF (lOmL) for 10 min. Themixture was then heated to 120C and stirred for 17h. The solvents were removed in vacua.The residue was stirred with methanol (5mL) and dichloromethane (lOmL) for 30min. Thesolids were collected by filtration, washed with dichloromethane (2mL) and water (3x8mL),and dried in vacua to afford the title compound as an off-white solid. ^-NMR (DMSO-d6,400 MHz): 8 = 8.74 (d, J= 2.8 Hz, 1 H), 8.77 (s, 1 H), 8.79 (d, J= 2.8 Hz, 1 H), 9.12 (s, 1 H),13.26 (s, br, 1 H). MS (ES+): m/z 224.09 [MH*]. HPLC: tR = 2.16 min (ZQ2000,polar_5min). |

---|---|---|
With trichlorophosphate; | B. 2-Chloro-3-iodo-5-nitropyridine (765B) 2-Hydroxy-3-iodo-5-nitropyridine (2.55 g, 9.5 mmol), phosphorous pentachloride (2.60 g, 12 mmol) and phosphorous oxychloride (2 mL) were combined in a flask under nitrogen and heated to 140 C. for 45 mins. The cooled reaction mixture was poured over ice to give a solid which was partitioned between CH2Cl2 and water. The organic layer was separated, washed with brine, dried (MgSO4), filtered, and the solvent was removed in vacuo to give compound 765B (2.25 g, 83%) as a yellow solid. HPLC: 98.5% at 2.75 min(YMC S5 ODS column) eluding with 10-90% aqueous methanol containing 0.2% phosphoric acid over a 4 min gradient monitoring at 220 nm. |

With potassium iodate; potassium iodide; In sulfuric acid; water; | A. 2-Hydroxy-3-iodo-5-nitropyridine (765A) 2-Hydroxy-5-nitropyridine (7.0 g, 50 mmol) was suspended in 100 mL of 20% sulfuric acid and then treated with potassium iodate (4.2 g, 19.6 mmol) dissolved in 10 mL of water. The mixture was heated to 100 C. and potassium iodide (8.0 g, 48.2 mmol) dissolved in 20 mL of water was added dropwise over one h. The reaction mixture turns a purplish-red and a precipitate forms. After 0.5 h, the reaction mixture is cooled and filtered. The solid is stirred for 15 min with 10% sodium meta-bisulfite solution, filtered, washed with water and dried at 80 C. overnight on a vacuum pump to give the desired compound 765A (12.32 g, 92%) as a yellow solid. The product was characterized by 1H NMR. |

With di-isopropyl azodicarboxylate; triphenylphosphine; In tetrahydrofuran; at 20℃; for 2h; | Example 1.9: Preparation of Intermediate 4-[2-(3-Iodo-5-nitro-pyridin-2-yloxy)-ethyl]- morpholine.To a suspension of <strong>[25391-58-6]3-iodo-5-nitro-pyridin-2-ol</strong> (1.95 g, 7.32 mmol) in THF (60 mL), triphenyl phosphine (4.09 g, 15.6 mmol) and 4-(2-hydroxyethyl)motaupholine (1.90 mL, 15.6 mmol) were added followed by dropwise addition of diisopropyl azodicarboxylate (DIAD) (3.00 mL, 15.5 mmol). After 1 hour, an LC/MS showed only partial conversion so extra triphenyl phosphine (2.73'g, 10.4 mmol) and 4-(2-hydroxyethyl)morpholine (1.30 mL, 10.7 mmol) were added followed by dropwise addition of diisopropyl azodicarboxylate (DIAD) (2.00 mL, 10.3 mmol). The reaction mixture was stirred at room temperature for 1 more hour and then concentrated. The resulting gummy residue was dissolved in water (500 mL), acidified with HCl to pH 1 , washed with ethyl acetate (three 300 mL portions, which were discarded), basified to pH 10 with NaOH, and extracted three times with 300 mL portions of ethyl acetate. The combined organic phase was dried over MgSO4, filtered and concentrated, yielding an oil which was purified by HPLC to afford 4-[2-(3-iodo-5-nitro-pyridin-2-yloxy)-ethyl] -morpholine as an impure brown oil (1.06 g). LCMS m/z (%) = 380 (M+H, 100). 1H NMR (400 MHz, DMSO-de) delta: 9.04 (d, J= 2.63 Hz, IH), 8.87 (d, J= 2.60 Hz, IH), 4.55 (t, J= 5.61 Hz, 2H), 3.58-3.50 (m, 4H), 2.75 (t, /= 5.59 Hz, 2H), 2.43-2.30 (m, 4H). |
