Procedure

Repeat Step (a) of EXAMPLE 6, but replace (1R,2S)-2-amino-1-phenyl-3-methyl-butanol with (1R,2S)-2-amino-1,2-diphenyl-ethanol, and replace 1,4-dibromobutane with 1,5-dibromopentane. Column chromatography (Silica gel 50 g, eluent is n-Hexane:EtOAc=5:1) is used to purify the coarse product and a white solid (1.28 g) is obtained. The yield is 91% and the other analysis includes:
