Procedure
2,6-Di(methoxymethoxy)benzeneboronic acid (0.25 g) was coupled with N-(2,6-dichlorobenzoyl)-O-(trifluoromethanesulfonyl)-L-tyrosine ethyl ester in a similar procedure as described in Example 5-3) to afford N-(2,6-dichlorobenzoyl)-4-[2,6-di(methoxymethoxy)phenyl]-L-phenylalanine ethyl ester. ESMS: m/z 562 (MH+).
