As a common heterocyclic compound, it belongs to benzoxazole compound, name is 2-Methylbenzo[d]oxazol-6-amine, and cas is 5676-60-8, its synthesis route is as follows.

General procedure: To a solution of compound 3 (3.37 mmol) in DMF (10 mL), charged respective compound V (a-p) (4.04 mmol) and heated to 80 C. After3 h, TLC analysis showed complete conversion of starting materials. The reaction mixture was cooled to room temperature, charged water (30 mL) and extracted with EtOAc (2 × 20 mL). The combined organic layer was washed with water (20 mL) followed by brine and concentrated under reduced pressure to obtain gummy liquid. This crude material was triturated with MTBE to afford desired product as solid and which used as such in next step without any further purification.
