Reaction Steps

N-(Toluene-4-sulfonyl)-L-proline hydrate was coupled to L-5-(1,1-dimethylethyl)-glutamic acid methyl ester hydrochloride using the procedure described in Method 3. The methyl ester was hydrolyzed using LiOH in THF/water to provide a solid, mp=164-166° C. The title compound was prepared, via cleavage of the t-butyl ester using trifluoroacetic acid in CH2Cl2, as a solid, mp=>200° C.
