Reaktionsschritte
(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 as described in Method B7a. 4-Cyano-3-(trifluoromethyl)aniline was converted to 4-cyano-3-(trifluoromethyl)phenyl isothiocyanate according to A2a, Step 3. The isothiocyanate was reacted with (1S)-1-(chloromethyl)-2-methylbutanammonium chloride according to Method C1a to give (4S)-2-(4-cyano-3-(trifluoromethyl)phenylimino)-4-(2-butyl)-1,3-thiazolidine. The thiazolidine was reacted with isobutyl bromide according to Method D2a to afford (4S)-2-(4-cyano-3-(trifluoromethyl)phenylimino)-4-(2-butyl)-3-isobutyl-1,3-thiazolidine.
