Procedure

A mixture of 3,4-dinitrophenol (250 mg), 4-(2-chloroethyl)morpholine hydrochloride (252 mg) and potassium carbonate (375 mg) in dimethylformamide (3 ml) was heated at 120° C. for 20 minutes in a Personal Chemistry Smith Creator microwave. The reaction mixture was partitioned between ethyl acetate and water and the organic layer dried over magnesium sulfate, filtered and the filtrate concentrated in vacuo to give 4-[2-(3,4-dinitro-phenoxy)-ethyl]-morpholine (319 mg) as a yellow oil. LC-MS (METHOD B): RT=2.13 minutes, 298 (M+H)+.
