実験手順
To a solution of N-[(4-chlorophenyl)-methyl]-2-hydroxy-6-methyl-4-morpholin-4-yl-benzamide (0.2 g, 0.56 mmol) in acetone (5 ml) are added potassium carbonate (0.092 g, 0.66 mmol) and ethyl iodide (0.066 ml, 0.83 mmol). The reaction mixture is stirred at 50° C. for 1 h. Additional ethyl iodide (0.22 ml, 2.77 mmol) is added and heating is continued for another 2 h. Additional ethyl iodide (0.22 ml, 2.77 mmol) is then added and the reaction mixture is stirred for 15 h. After completion of reaction, the solution is filtered through a pad of celite and concentrated to obtain the crude product, which is purified by column chromatography (silica gel, 15% ethyl acetate/hexan) yielding N-[(4-chlorophenyl)-methyl]-2-ethoxy-6-methyl-4-morpholin-4-yl-benzamide (example 11) (0.12 g, 0.3 mmol, 56%). [M+H]+ 389.2.
