69% | With acetic acid; at 150℃; for 0.0833333h;Microwave irradiation; | EXAMPLE 1:; 2-phenylpyrazolori,5-alphalquinazolin-5(4//)-one; A solution (0.66 M) of <strong>[33906-30-8]2-hydrazinobenzoic acid hydrochloride</strong> (from Aldrich) in AcOH was treated with benzoylnitrile (1 eq.). The reaction mixture was heated at 1500C under microwave irradiation for 5 min. The resulting precipitate was filtered, washed with Et2O and dried to afford(69%) the title compound as a solid.1U NMR (400 MHz, DMSO-de, 300K) delta 6.38 (s, IH), 7.40 (t, J 7.6 Hz, IH), 7.48 (t, J 7.6 Hz,2H), 7.51 (t, J7.6 Hz, IH), 7.91 (t, J7.6 Hz, IH), 7.97 (d, J7.6 Hz, 2H), 8.17-8.14 (m, 2H),12.31 (s, IH).

With triethylamine; In N,N-dimethyl-formamide; at 90.0℃; for 16.0h; | General procedure: 1H-Pyrazol-5-amine 1 (1 equiv.), 3-oxopropanenitrile 2 (1 equiv.), benzaldehyde 3 (1 equiv.), and Et3N (2 equiv.) were stirred in DMF (1 M) at 90 C for 16 h. The volatiles were removed under reduced pressure (or positive N2 (g) pressure). Sodium nitrite (3 equiv.) and acetic acid (134 equiv.) were added to the crude material, and the reaction mixture was stirred for 10 min. The volatiles were removed under reduced pressure (or positive N2 (g) pressure), and the crude reaction mixture was subjected to silica gel column chromatography with ethyl acetate in hexanes. |
