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. 2,3-Dichlorophenyl isothiocyanate was reacted with (1S)-1-(chloromethyl)-3-methylbutanammonium chloride according to Method C1a to give (4S)-2-(2,3-dichlorophenylimino)-4-isobutyl-1,3-thiazolidine. The thiazolidine was reacted with 3-bromopentane according to Method D2a to afford (4S)-2-(N-(3-pentyl)-2-methyl-4-nitrophenylamino)-4-isobutyl-1,3-thiazoline.
