Versuchsvorschrift
A sealed tube was charged sequentially with 2-ethynylfuran (153 mg, 1.663 mmol), 1-chloro-4-iodobenzene (395 mg, 1.663 mmol), L-proline (38.2 mg, 0.332 mmol), Na2CO3 (35 mg, 0.332 mmol), sodium ascorbate (66 mg, 0.332 mmol), DMSO-H2O (9:1; 7 ml), NaN3 (130 mg, 1.99 mmol) and CuSO4.5H2O (415 mg, 1.663 mmol). The tube was sealed and stirred at 65° C. for 16 hours. The reaction mixture was poured onto cold ammonium hydroxide solution, and the mixture was extracted with ethyl acetate (3×30 ml). The combined organic layers were washed with brine solution (30 ml), dried over sodium sulfate and evaporated to yield the crude material, which was purified by column chromatography with 20% ethyl acetate/hexane yielding 1-(4-chlorophenyl)-4-(furan-2-yl)-1H-1,2,3-triazole (20 mg, yield 4.9%) as a pale yellow solid. The HPLC purity was 98.02%. LC-MS [M+H] 246 (C12H8ClN3O+H, expected 246.04). The 1H-NMR spectra was in accordance with the chemical structure.
