Reaction Steps

1,1-Dimethyl-2-hydroxyamine was converted to 1,1-dimethyl-2-chloroethylammonium chloride according to Method B7a. 2-Methyl-4-nitrophenyl isothiocyanate was reacted with 1,1-dimethyl-2-chloroethylammonium chloride according to Method C1a to give 2-(2-methyl-4-nitrophenylimino)-4,4-dimethyl-1,3-thiazolidine. The thiazolidine was reacted with 2-methylprop-2-en-1-yl bromide according to Method D2g to afford 2-(2-methyl-4-nitrophenylimino)-4,4-dimethyl-3-(2-methylprop-2-en-1-yl)-1,3-thiazolidine HBr salt.
