(1S)-1-Phenyl-2-hydroxyethylamine was converted to (1S)-2-chloro-1-phenylethylammonium chloride according to Method B7b. 2-Methyl-4-nitrophenyl isothiocyanate was reacted with (1S)-2-chloro-1-benzylethylammonium chloride according to Method C1a to give (4S)-2-(2-methyl-4-nitrophenylimino)-4-phenyl-1,3-thiazolidine. The thiazolidine was reacted with isobutyl bromide according to Method D2a to afford (4S)-2-(2-methyl-4-nitrophenylimino)-4-phenyl-3-isobutyl-1,3-thiazolidine HCl salt.
