Versuchsvorschrift
A solution of T3P in AcOEt (50%, 26.2 mL, 44.0 mmol) was added dropwise at 0° C. under N2 to a clear solution of 2-(2-iodophenyl)ethanamine (9.45 g, 38.2 mmol), 3-methoxy-2-methyl-3-oxopropanoic acid (5.05 g, 38.2 mmol) and Et3N (10.7 mL, 76.0 mmol) in AcOEt (350 mL). The mixture was stirred at RT for 6 days. A 2N aqueous solution of NaOH (50 mL) was then added to the reaction and the mixture was extracted with AcOEt. The combined org. layers were then dried over Na2SO4, filtered and concentrated in vacuo. The yellow oil obtained was purified by flash chromatography (SiO2, cHEx/AcOEt 100:0 to 50:50) to afford the title compound (10.83 g) as a clear oil. UPLC-MS: MS 362.2 (M+H+); UPLC rt 0.95 min.
