A new method for the preparation of <I>t</I>-butyloxycarbonyl amino acids and <I>p</I>-methoxybenzyloxycarbonyl amino acids has been devised. The former was obtained in satisfactory yields from amino acids and <I>t</I>-butyl <I>S</I>-4,6-dimethylpyrimid-2-ylthiocarbonate prepared from <I>t</I>-butyl alcohol and (4,6-dimethylpyrimid-2-ylthio)corbonyl chloride in dry pyridine, and the latter was also obtained from amino acids and <I>p</I>-methoxybenzyl <I>S</I>-4,6-dimethylpyrimid-2-ylthiocarbonate from <I>p</I>-methoxybenzyl alcohol and (<I>S</I>-4,6-dimethylpyrimid-2-ylthio)carbonyl chloride. These <I>t</I>-butyloxycarbonylation and <I>p</I>-methoxybenzyloxycarbonylation of amino acids are more convenient than the usual methods.
