反応手順

(1S)-1-(Hydroxymethyl)-3-methylbutylamine was converted to (1S)-1-(chloromethyl)-3-methylbutanammonium chloride as described in Method B7a. 2,6-Dimethyl-4-nitroaniline was converted into 2,6-dimethyl-4-nitrophenyl isothiocyanate according to Method A2b. 2,6-Dimethyl-4-nitrophenyl isothiocyanate was reacted with (1S)-1-(chloromethyl)-3-methylbutanammonium chloride according to Method C1a to give (4S)-2-(2-methyl-4-nitrophenylimino)-4-isobutyl-1,3-thiazolidine. The thiazolidine was reacted with isobutyl bromide according to Method D2a to give (4S)-2-(2,6-dimethyl-4-nitrophenylimino)-3,4-diisobutyl-1,3-thiazolidine HCl salt.
