摘要
This invention relates to new processes for manufacturing 4-[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]-N-methyl-3H-[1,2,3]triazole-5-carboxamide (compound I) as well as the following new intermediates useful in these synthetic processes. 2-benzenesulfonyl-N-methylacetamide (compound IV), 2-(benzenesulfonyl)-3-[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]-N-methylacrylamide (compound II) and threo-2-[2-benzenesulfonyl-1-[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]-2-[(methylcarbamoyl)ethyl]]-5-[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]-N-methyl-2H-[1,2,3]triazole-4-carboxamide (compound III).
