Name is Benzo[d]oxazol-2-amine, as a common heterocyclic compound, it belongs to benzoxazole compound, and cas is 4570-41-6, its synthesis route is as follows.
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 °C. 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).
4570-41-6, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,4570-41-6 ,Benzo[d]oxazol-2-amine, other downstream synthetic routes, hurry up and to see
