Reaction Steps

To a cooled solution of 4-methoxy-2-nitroaniline (25 g; 0.15 mol) in pyridine (370 ml), ethyl chloroformate (17.8 ml; 0.18 mol) was added dropwise. The mixture was refluxed for 10 hours, then cooled and poured into ice-water. The precipitated solid was collected and purified by flash chromatography (silica gel, eluent: hexane/diethyl ether 85:15) to yield the title compound as a yellow solid. 7.3 g; m.p. 56-57° C.
