Procedure
1-Chloro-2-nitroaniline (13 g, 0.082 mole) and 17.15 ml of cyclopropylamine were heated together at reflux temperature for 24 hours, cooled and poured into ethyl acetate. The organic solution was washed with a saturated brine solution (3×100 ml), dried with magnesium sulfate and concentrated to dryness. The residue was chromatographed on silica gel using 60% hexane in chloroform to give 2.04 g of the desired intermediate.
