Procedure

A solution of 14-4 (0.110 g, 0.39 mmol), β-aminoester 6-6 (0.106 g 0.39 mmol), EDC (0.075 g, 0.39 mmol), HOBT (0.053 g, 0.39 mmol) and N-methylmorpholine (0.164 mL, 1.17 mmol) in degassed DMF (5 mL) was stirred at room temperature for 12 h. The solution was concentrated. The residue was purified by flash chromatography to give 14-5.
