Procedure
Methyl-2-tert-butoxycarbonylamino-3-(3,5-dibromo-4-hydroxyphenyl)-propionate (0.20 g, 0.44 mmol) was coupled with 3,5-dimethyl benzylbromide (0.22 g, 1.1 mmol), using the method described in Example 2. After deprotection and final purification on HPLC, using the same conditions as described in Example 1(b), 70 mg (35%) of 2-amino-3-[3,5-dibromo-4-(3,5-dimethylbenzyloxy)phenyl]propionic acid was obtained. LC-MS (electrospray): m/z 458 (M+1).
