Reaction Steps
To a degassed solution of 3-[2-(4-bromo-phenyl)-thiomorpholin-4-yl]-propionic acid tert-butyl ester (22.15 g; 57.33 mmol) and N,N′-dimethylethylenediamine (3.05 mL; 28.7 mmol) in 1,4-dioxane (250 mL) was added CuI (1.09 g; 5.73 mmol), and NaI (21.48 g; 143.33 mmol). The resulting mixture was heated at 130° C., for 4 days, in sealed flask. After cooling to RT the mixture was concentrated in vacuol and purified by column chromatography (SiO2, Et2O/hexanes 2:3) to afford 3-[2-(4-iodo-phenyl)-thiomorpholin-4-yl]-propionic acid tert-butyl ester (19.30 g).
