Procedure

A mixture of N-ethyl-N-methyl 2-(N-tert-butylamino)benzamide (1.89 g, 8.1 mmol), potassium carbonate (2.2 g, 15.9 mmol), and methyl iodide (2.3 g, 16.2 mmol) in DMF (40 mL) was heated overnight at 40° C., then was partitioned between EtOAc and water. The EtOAc was dried (MgSO4), concentrated, and purified by HPLC with 1:4 ethyl acetate/cyclohexane to afford 1.923 g of N-ethyl-N-methyl 2-(N-methyl-N-tert-butylamino)benzamide as a yellow oil, a 96% yield.
