Procedure

N-(2,6-Dichlorobenzoyl)-4-(2,6-dimethoxy-3methoxymethoxyphenyl)-L-phenylalanine methyl ester (165 mg) was dissolved in MeOH (5 mL) and HCl in dioxane (4 M, 1 mL) was added to the mixture. The mixture was stirred at room temperature for 3 h. The mixture was evaporated and the residue was taken up with water (40 mL) and extracted with CH2Cl2. The extract was dried (MgSO4), filtered and evaporated. The residue was purified by preparative TLC (silica gel; eluent: hexane and AcOEt 3:1 to 1:1) to give N-(2,6-dichlorobenzoyl)-4-(2,6-dimethoxy-3-hydroxyphenyl)-L-phenylalanine methyl ester (145 mg ).
