実験手順
Repeat Step (a) of EXAMPLE 6, but replace (1R,2S)-2-amino-1-phenyl-3-methyl-butanol with (1R,2S)-2-amino-1,2-diphenylethanol, and replace 1,4-dibromobutane with (BrC2H4)2O. Column chromatography (Silica gel 50 g, eluent is n-Hexane:EtOAc=4:1) is used to purify the coarse product and a white solid (1.34 g) is obtained. The yield is 95% and the other analysis includes:
