Procedure
A solution of 10-(4-fluoro-phenyl)-dec-9-enoic acid (230 mg, 0.87 mmol), oxalyl chloride (0.11 mL, 1.3 mmol), and N,N-dimethylformamide (one drop) in dichloromethane (3 mL) was stirred at room temperature for 2 hours, then volatile material was removed by distillation to afford 10-(4-fluoro-phenyl)-dec-9-enoyl chloride. This was redissolved in dichloromethane, then N,N-diisopropylethylamine (140 mg, 1.04 mmol) was added dropwise, followed by (R)-3-amino-4-dimethylamino-butyric acid benzyl ester dihydrochloride. The reaction mixture was stirred at room temperature for 16 h, then washed with water. The organic layer was evaporated and the residue purified by preparative HPLC to afford (R)-4-dimethylamino-3-[10-(4-fluoro-phenyl)-dec-9-enoylamino]-butyric acid benzyl ester (100 mg, 24%), m/e=483.4 ([M+H]+).
