Procedure

A solution of (2R)-2-(2-tert-butoxy-2-oxoethyl)-5-cyclohexylpentanoic acid (Preparation 1) (500 mg, 1.67 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (354 mg, 1.85 mmol), N-methylmorpholine (203 l, 1.85 mmol) and 1-hydroxybenzotriazole hydrate (227 mg, 1.67 mmol) in dichloromethane (20 ml) was treated with (1Z)-N′-hydroxy-2-(propylsulfonyl)ethanimidamide (300 mg, 1.67 mmol) and stirred at room temperature for 18 hours. The reaction mixture was diluted with water (10 ml) and stirred for 20 minutes. The layers were separated via a 5 micron filter cartridge. The organic solvent was removed under reduced pressure to afford the title compound as a yellow solid (760 mg).
