Reaction Steps

(1S)-1-(Hydroxymethyl)-3-methylbutylamine was made from (L)-leucine methyl ester as described in Method B1b. The 2-hydroxyethylamine was converted to (1S) -1-(chloromethyl)-3-methylbutanammonium chloride as described in Method B7a. 2-Chloro-4-cyano-6-methylphenyl isothiocyanate was reacted with (1S)-1-(chloromethyl)-3-methylbutanammonium chloride according to Method C1c to give (4S)-2-(2-chloro4-cyano-6-methylphenylimino)-4-isobutyl-1,3-thiazolidine. The thiazolidine was reacted with isobutyl bromide according to Method D2f to afford (4S)-2-(2-chloro-4-cyano-6-methylphenylimino)-3,4-diisobutyl-1,3-thiazolidine trifluoroacetate salt.
