## Abstract Ethyl 3,4‐dihydro‐2__H__‐1,4‐benzoxazine‐3‐carboxylate derivatives **2** were obtained and isolated in low yields from the condensation of 2‐aminophenol and ethyl 2,3‐dibromopropanoate. They can be obtained by hydrogenation of ethyl 2__H__‐1,4‐benzoxazine‐3‐carboxylate in satisfactory y
