Versuchsvorschrift
(1S)-1-(Hydroxymethyl)-2-methylbutylamine was made from (L)-isoleucine methyl ester as described in Method B1b. The 2-hydroxyethylamine was converted to (1S)-1-(chloromethyl)-2-methylbutanammonium chloride as described in Method B7a. 5-Aminoindan-1-one was converted to 1-oxo-5-indanyl isothiocyanate according to Method A2a. The isothiocyanate was reacted with (1S)-1-(chloromethyl)-2-methylbutanammonium chloride to Method C1a to give (4S)-2-(1-oxo-5-indanylimino)-4-(2-butyl)-1,3-thiazolidine. The thiazolidine was reacted with isobutyl bromide according to Method D2a to afford (4S)-2-(1-oxo-5-indanylimino)-4-(2-butyl)-3-isobutyl-1,3-thiazolidine.
