実験手順

(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-Methyl-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 cyclopropylmethyl bromide according to Method D2a to afford (4S)-2-(2-methyl-4-nitrophenylimino)-4-isobutyl-3-(cyclopropylmethyl)-1,3-thiazolidine.
