Reaction Steps

A mixture of 3-[2-(4-Acetylsulfanyl-phenyl)-morpholin-4-yl]-propionic acid tert-butyl ester (0.31 g; 0.85 mmol) and NaOH (37 mg, 0.93 mmol) in EtOH (10 mL) and water (1 mL) was stirred for 30 min at 0° C. Subsequently, 2,6-dichlorobenzyl bromide (0.22 g; 0.93 mmol), dissolved in EtOH (2.5 mL), was added, and the mixture allowed to warm to RT. After 90 min. the mixture was partitioned between EtOAc and 5% aqueous NaHCO3. The layers were separated, and the organic layer was washed with 5% aqueous NaHCO3 and brine, dried (Na2SO4), filtered and concentrated in vacuo. The residue was purified by column chromatography (SiO2, CH2Cl2/acetone 95:5) to afford 3-{2-[4-(2,6-dichloro-benzylsulfanyl)-phenyl]-morpholin-4-yl}-propionic acid tert-butyl ester (0.20 g).
