With hydrogenchloride; iron; In methanol; at 8 - 16℃; for 16.0h; | General procedure for the synthesis of U2To a stirred solution of Ui in MeOH (100 mL) were added concentrated HC1 (9 mL, 108 mmol, 1 2M) and iron powder (10.0 g, 179 mmol). The reaction mixture was stirred at 8-16C for 16 hours. After reaction was completed, the mixture was filtered. The filtrate was neutralized to pH 8 with NaHCO3 aqueous solution and filtered. The filtrate was extracted with EtOAc (100 mLx2). The combined extracts were washed with brine (200 mL), dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford U2. |

76% | In chloroform; at 60℃; for 12.0h;Inert atmosphere; | To a solution of <strong>[16429-44-0]5-bromo-3-chlorobenzene-1,2-diamine</strong> (200 mg,0.90 mmol)inchloroform (3 mL)was added di(1H-imidazol-1-yl)methanone (220 mg,1.35 mmol). The mixture was heated to 60 C for 12 h under a nitrogen atmosphere. After cooling the reaction toroom temperature,the white precipitate was filtered off,washed with chloroform (3 mL x 2),and dried in vacuo to give the title compound (170 mg,76%)as a white solid. 1H NMR (400MHz,DMSO-d6)8 11.35 (s,1H),11.05 (s,1H),7.21 (d,J = 1.6 Hz,1H),7. 04 (d,J = 1.6 Hz,1H). |
In tetrahydrofuran; for 16.0h;Reflux; | General procedure for the synthesis of U3A mixture of U2 (7.2 g, 32.5 mmol) and CDI (6.32 g, 39.0 mmol) in anhydrous THF (100 mL) was refluxed for 16 hours. After cooling to room temperature, the white precipitate was collected by filtration and dried under reduced pressure to afford U3. |
