Methyl aminoisobutyric acid was converted to methyl aminoisobutyrate HCl salt according to method B1c, Step 1. The ester was reduced to 3-hydroxy-2-methyl-2-propylamine according to Method B1c, Step 2. The 2-hydroxyethylamine was treated with SOCl2 according to Method B7b, followed by 2-methyl-3-nitrophenyl isothiocyanate according to Method C1a to give 2-(2-methyl-4-nitrophenylimino)-4,4-dimethyl-1,3-thiazolidine. The thiazolidine was reacted with isobutyl bromide according to Method D2a to afford 2-(2-methyl-4-nitrophenylimino)-4,4-dimethyl-3-isobutyl-1,3-thiazolidine.
