A mixture comprising 2-(2-methoxyphenoxy)ethylamine (10 g, 59.9 mmol), diisopropylethylamine (13.9 mL, 81.6 mmol) and dichloromethane (80 mL) was cooled to 0° C. and then a solution of 3-methoxy-4-nitrobenzoyl chloride (11.76 g, 54.4 mmol) in dichloromethane (50 mL) was added dropwise. The mixture was allowed to warm to 23° C. over two hours, quenched with aqueous hydrochloric acid (3M, 20 mL), washed with water (3×20 mL), dried (Na2SO4) and concentrated in vacuo to provide N-[2-(2-methoxyphenoxy)ethyl]-3-methoxy-4-nitrobenzamide (14 g, 74% yield) an off white solid; MS (PB-PCI) C17H18N2O6 m/e calc 346.34; found 347 (MH+).
