Procedure

A solution of 8.3 g (36.1 mmol) of (2S)-1-chloro-2-hydroxy-3-N-mesylisopropylaminopropane and 8.69 g (43.4 mmol) of p-benzyloxyphenol in 75 ml DMSO was treated with 10.86 ml 4 N NaOH (43.4 mmol) and the mixture was heated at 100° for 5 hours. To the cooled reaction mixture 40 ml 1 N NaOH and 60 ml H2O were added with stirring and the resulting solid was collected by filtration and was washed well with H2O. The dried crude product was recrystallized from EtOAc-hexane to yield the end product as white needles, mp 93°-94°.
