Yield: 79%

Reaction Conditions:

with potassium carbonate in toluene at 140; for 24 h;Schlenk technique;Sealed tube;

Steps:

12 Embodiment 12
In a clean dry 10 ml Schlenk reaction tube, sequentially adding a 2-nitro-N-methylaniline 38 mg, benzene glycine 113 mg, potassium carbonate 80 mg, in order to 1 ml of toluene as a solvent, the reaction tube seal, in 140 °C reaction under 24 hours. After the reaction, the reaction mixture directly by rotating the evaporimeter turns on lathe does, then the volume ratio of 8:1 of petroleum ether and ethyl acetate as the eluant, by separating by silica gel column, to obtain 39 mg light yellow solid, yield 79%.
