To a mixture of 2-nitrobenzoyl chloride (0.3 mL, 2.05 mmol) and (1-aminomethyl-cyclohexyl)-acetic acid methyl ester hydrochloride (500 mg, 2.25 mmol) (prepares according to example A) in dichloromethane (10 mL) is added DIPEA (0.75 mL, 4.02 mmol). The mixture is stirred at room temperature for 16 hours. The reaction mixture is concentrated and the resulting residue is purified by flash chromatography with 50% EtOAc in Hexane as the eluent to afford the desired {1-[(2-nitro-benzoylamino)-methyl]-cyclohexyl}-acetic acid methyl ester (680 mg, 99%).
