PROCEDURE

实验过程

These compounds namely, 3-[4-chloro-2-hydroxy-3-((S)-4-hydroxy-isoxazolidine-2-sulfonyl)-phenylamino]-4-ethoxy-cyclobut-3-ene-1,2-dione (Intermediate FC) and 3-[4-chloro-2-hydroxy-3-((R)-4-hydroxy-isoxazolidine-2-sulfonyl)-phenylamino]-4-ethoxy-cyclobut-3-ene-1,2-dione (Intermediate FD) are prepared analogously to 6-chloro-3-(2-ethoxy-3,4-dioxo-cyclobut-1-enylamino)-2-hydroxy-N-methoxy-N-ethyl-benzenesulfonamide (Intermediate FA) by replacing N-ethyl-O-methylhydroxylamine hydrochloride (Intermediate G) with hydrochloride salts of either (S)-isoxazolidin-4-ol (Intermediate I) or (R)-isoxazolidin-4-ol (Intermediate J). [M+H]+ 418.9 and [M+H]+ 418.9.
