실험 절차

K2CO3 (4.76 mmol) is added to a solution of 3,4-dihydro-2H-benzo[1,4]oxazine-8-carboxylic acid methyl ester (2.07 mmol) in DMF (3.0 mL). After 30 min methyl iodide (4.14 mmol) is added and the mixture is stirred for 2 h at 75° C. Cold water and EtOAc are added, the layers are separated and the aq. layer is extracted with EtOAc. The combined organic layers are washed with water and brine, dried over MgSO4 and concentrated in vacuo to give a crude product which is used without further purification. LC-MS: tR=0.83 min; [M+H]+=208.1.
