合成路线1
该中间体在本合成路线中的序号：(II)Silylation of 4-benzyloxyindole (I) employing tert-butyldimethylsilyl chloride and NaH gave the N-silyl derivative (II), which was brominated with N-bromosuccinimide at -78 C to afford the 3-bromoindole (III). After lithium-bromine exchange with n-BuLi at -78 C, the 3-lithio compound was condensed with N-methyl-D-proline methyl ester (IV) to give the indolyl ketone (V). The ketone function of (V) was finally reduced employing LiAlH4 in boiling dioxan, with concomitant cleavage of the benzyl ether to furnish the title compound.
