4570-41-6, Benzo[d]oxazol-2-amine is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,4570-41-6
The reaction mixture of 2-aminobenzoxazole (0.25 g; 1.86 mmol) and salicylaldehyde (0.230 g; 1.86 mmol) dissolved in 40 cm3 of dry toluene containing 3 drops of piperidine was heated at reflux temperature for 6 hours under nitrogen. The initial yellow solution of the reaction mixture turned orange and was allowed to cool down to room temperature after the reflux period and thereafter left overnight in the fridge in order to induce precipitation. The resultant yellow precipitate was filtered and washed with cold anhydrous toluene and petroleum ether. Yield = 80percent, M.P. = 136 ? 138 ¡ãC. IR (numax/cm-1): nu(N-H) 3339, nu(O-H) 3056 (w), nu(C=O) 1706 (m), nu(C=N) 1601 (vs), nu(C-N) 1244 (s). 1H NMR (295K/ppm, see Fig. S2): 9.68 (s, 1H, NH), 7.98 (d, 1H, H5), 7.75 ? 7.67 (m, 2H, H2, H3), 7.54 (t, 1H, H4), 7.43 ? 7.35 (m, 2H, H10, H11), 7.07 ? 6.98 (m, 2H, H9, H12), 3.36 (br, s, 1H, OH). UV-Vis (DMF, (lambdamax (epsilon, M-1cm-1))): 241 nm (10974); 282 nm (8712); 330 nm (15707); 351 nm (16979); 383 nm (20673).
The synthetic route of 4570-41-6 has been constantly updated, and we look forward to future research findings.
