合成路线1
该中间体在本合成路线中的序号：(III)The reaction of 8(S)-(bromomethyl)-4-hydroxy-2-methyl-1-oxo-6-(5,6,7-trimethoxyindol-2-ylcarbonyl)-1,2,3,6,7,8-hexahydrobenzo[1,2-b:4,3-b']dipyrrole-2-carboxylic acid methyl ester (I) with tert-butyl-dimethylsilyl chloride in DMF gives the corresponding O-silyl derivative (II), which is treated with camphorsulfonic acid (CPS) in hot chloroform to afford 8(S)-(bromomethyl)-4-hydroxy-2-methyl-6-(5,6,7-trimethoxyindol-2-ylcarbonyl)-3,6,7,8-tetrahydrobenzo[1,2-b:4,3-b']dipyrrole-1-carboxylic acid methyl ester (III). Finally, this compound is desilylated with tetrabutylammonium fluoride in THF and condensed with N-methylpiperazine (IV) and 4-nitrophenyl chloroformate by means of triethylamine in dichloromethane.
