Participants

Reaction Steps

By employing a procedure similar to that described in Example XVI, Part A, 3-(ethoxycarbonylmethoxymethyl)-4-(p-methoxybenzyl)-1,2,4-triazole-5-thiol was prepared from ethoxycarbonylmethoxyacetohydrazide. The ethoxycarbonyl group was then hydrolyzed to the free acid using aqueous 2 N sodium hydroxide, and the p-methoxybenzyl blocking group was thereafter removed by using trifluoroacetic acid in a manner similar to that earlier described in Example XVI, Part B to finally give pure 3-(carboxymethoxymethyl)-1,2,4-triazole-5-thiol, m.p. 180°-182° C.
