Reaction Steps

(R)-N-isobutylserine methyl ester HCl salt was made from (D)-serine methyl ester as described in Method B3a. The ester was reacted with SOCl2, followed by 2-methyl-4-nitrophenyl isothiocyanate according to Method C2a to afford (4S)-2-(2-methyl-4-nitrophenylimino)-4-(methoxycarbonyl)-3-isobutyl-1,3-thiazolidine HCl salt.
