Procedure
(1S)-1-(Hydroxymethyl)-2-methylbutylamine was made from (L)-isoleucine methyl ester as described in Method B1b. The 2-hydroxyethylamine was converted to (1S)-1-(chloromethyl)-2-methylbutanammonium chloride an described in Method B7a. 2,5-methylaniline was converted to 2,5-dimethyl-4-nitrophenyl isothiocyanate according to Method A2a. 2,5-Dimethyl-4-nitrophenyl isothiocyanate was reacted with (1S)-1-(chloromethyl)-2-methylbutanammonium chloride to Method C1a to give (4S)-2-(2,5-dimethyl-4-nitrophenylimino)-4-(2-butyl)-1,3-thiazolidine. The thiazolidine was reacted with isobutyl bromide according to Method D2a to give (4S)-2-(2,5dimethyl-4-nitrophenylimino)-4-butyl-3-isobutyl-1,3-thiazolidine.
