Part A. 4-[(2-Chloro-acetyl)-methyl-amino]-benzoic acid (0.23 g, 1.0 mmol.) was stirred in DMF (2 mL) at RT under N2. (2-Amino-cyclohexyl)-carbamic acid tert-butyl ester (0.21 g, 1.0 mmol), HATU (0.57 g, 1.5 eq) and DIEA (0.5 mL, 2.9 eq) were added. The mixture was stirred at RT for 30 min. It was partitioned between EtOAc and water. The organic layer was washed with brine, dried over MgSO4, filtered, and concentrated to dryness to give (2-{4-[(2-chloro-acetyl)-methyl-amino]-benzoylamino}-cyclohexyl)-carbamic acid tert-butyl ester (0.40 g, yield: 95%).
