Procedure

A mixture of m-phenylenediamine (2.00 g), cyclohexanecarboxylic acid (2.37 g), HOBt (2.75 g) and EDCI (3.9 g) in DMF (20 mL) was stirred at ambient temperature for 2 hours. The reaction mixture was diluted with water and the resulting solid was collected by filtration. The solid was purified by silica gel column chromatography (hexane/ethyl acetate=4/1 to 1/2 v/v) to give N-(3-aminophenyl)cyclohexanecarboxamide (2.2 g) as a white powder.
