A new method for the syntheses of p-methoxybenzyl p-nitrophenyl carbonate, p-methoxybenzyl carbazate, and p-methoxybenzyloxycarbonyl amino acids has been devised. These compounds were obtained in satisfactory yield from sodium p-nitrophenolate, 85% hydrazine hydrate, and several amino acids with p-methoxybenzyl chloroformate prepared from anisyl alcohol and phosgene in the presence of dimethylaniline in dry ether at -5–-10°C. This direct p-methoxybenzyloxycarbonylation of amino acid with the chloroformate is more convenient than the usual Weygand method. |
