The invention provides a synthetic method of (purin-6-yl)amino acids which are useful as medicaments of anticancer, anti-virus agents and so on or their intermediates. Methyl (R, S)-3-[4-(9-benzylpurin-6-yl) phenyl]-2-[ (t-butoxycarbonyl) amino] propanoate is produced by making 9-benzyl-6-iodopurine react with methyl (R, S)-2-[ (t-butoxycarbonyl) amino]-3-[4-(trimethylstananyl) phenyl] propionate in the presence of Pd2dba3, triphenylarsine and copper iodide.
