Procedure

2-(1H-Benzotriazol-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (75 mg) was added to a solution of 5-(4-{(S)-1-[(S)-6-(2-hydroxy-2-methyl-propyl)-2-oxo-6-phenyl-[1,3]oxazinan-3-yl]-ethyl}-phenyl)-pyridine-2-carboxylic acid (0.10 g) and diisopropylethyl-amine (50 μL) in N,N-dimethylformamide (1 mL) at room temperature. The resulting solution was stirred for 25 min, before ethylamine (70% in water, 50 μL) was added. The solution was stirred at room temperature overnight and then concentrated under reduced pressure. The crude product was purified by HPLC on reversed phase (MeCN/H2O) to afford the title compound as a foam-like solid.
