Participants

Reaction Steps

To a solution of 4-benzyl-6-(3-chloro-4-hydroxy-phenyl)-morpholin-3-one (13.05 g; 39.0 mmol) in THF (600 mL) was added portionwise LiAlH4 (4.44 g; 117.04 mmol) at 0° C. The resulting mixtures was allowed to warm to RT and stirred overnight. Subsequently, the mixture was cooled to 0° C., and water (4.5 mL), a 2M aqueous NaOH-solution (9.0 mL) and water (9.0 mL) were added consecutively. Thereafter the mixture was stirred for 1 h. The formed precipitate was removed by filtration over kieselguhr, and washed with EtOAc. The organic solution was concentrated in vacuo, and the residue purified by column chromatography (SiO2, CH2Cl2/MeOH 98:2) to afford 4-(4-benzyl-morpholin-2-yl)-2-chloro-phenol (9.10 g)
