摘要

Conjugate addition of thiopheno15 to 3 (DMAP, THF, reflux) gave the thioether 4 in quantitative yield. Conversion of 4 to 5 was accomplished by lithium aluminum hydride (LiA1H4) reduction6 of the nitro group in an ether/THF solvent mixture under reflux conditions, the re-sulting primary amine (76%) was N-formylated with acetic formic anhydride (AFA)'in THF at-15 OC to give crys-talline (ethyl acetate-hexane) 5 in 91% yield. ...
