Procedure

Combine 3-(4-chloro-pyridin-3-yl)-5-methyl-isoxazole-4-carboxylic acid (0.50 g, 0.0021 mol) with (3-amino-cyclohexylmethyl)-carbamic acid benzyl ester (0.63 g, 0.0021 mol), 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (0.40, 0.0021 mol), 1-hydroxy-7-azabenzo-triazole (0.29 g, 0.0021 mol), and N,N-diisopropylethyl amine (1.10 mL, 0.0063 mol), in N,N-dimethylformamide (10 mL) and stir overnight at ambient temperature. Concentrate in vacuo and take up in water and extract with ethyl acetate. Wash the combined extracts with water and dry over sodium sulfate. Concentrate and elute over silica gel using methanol/dichloromethane to give 0.67 g (66%) of the desired amide. MS(ES): (M+1)+ 483.2, 485.2 m/z.
