It is a common heterocyclic compound, the benzoxazole compound, 2-Methylbenzo[d]oxazol-6-amine, cas is 5676-60-8 its synthesis route is as follows.
A slurry of 4-amino-2-methylquinoline (0.158 g) in dichloromethane (10 ml) was added to solution of carbonyl diimidazole (0.162 g) in dichloromethane (5 ml). The mixture was stirred for 2.5 h, solvent removed at reduced pressure and the residue dissolved in dimethylformamide (15 ml). 6-Amino-2-methylbenzoxazole (0.148 g) (Res. Inst. Drugs, Modra, Slovakia. Collect. Czech. Chem. Commun. (1996), 61, 371-380) was added and the mixture warmed to 100 C. for 1 h. Solvent was removed at reduced pressure and triturated with diethyl ether and methanol to give the title compound (0.035 g) as a colourless solid. 1 H NMR delta: 2.59 (3H, s), 2.60 (3H, s), 7.24 (1H, dd, J=1.9, 8.5 Hz), 7.58-7.63 (2H, m), 7.73 (1H, t, J=7.2 Hz),7.89 (1H, d, J=7.7 Hz), 8.06 (1H, d, J=1.8 Hz), 8.13-8.15 (2H, m), 9.22 (1H, brs), 9.55 (1H, brs). m/z (API+): 333 (MH+).
5676-60-8, 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.,5676-60-8 ,2-Methylbenzo[d]oxazol-6-amine, other downstream synthetic routes, hurry up and to see
