该中间体在本合成路线中的序号:(III)

The reaction of 6-bromo-1H-indole (I) with Tips-Cl and NaH in DMF gives the N-silylated indole (II), which is condensed with 1,4-diazabicyclo[4,3,0]nonane (III) by means of tBu-ONa, Pd(OAc)2 and tBu3P in hot xylene to yield the corresponding adduct (IV). The desilylation of (IV) by means of TBAF in THF affords the deprotected indole (V), which is finally sulfonated with 1-naphthylsulfonyl chloride and NaHMDS in THF.
