A common feature of many neuroleptic drugs available on the market today is the 4-amino-5- chloro-2-methoxybenzoic acid moiety.* V2 During a program of synthesizing a number of these drugs and their radiolabelled analogues for evaluation as potential Positron Emission Tomography imaging agents, we needed to develop a convenient synthesis of the parent acid. Published syntheses involved protectiondeprotection of the nitrogen? to prevent ...
