合成路线1
该中间体在本合成路线中的序号：(XVI)4) The condensation of hydrazine (II) with 3-nitropropanal (XIV) in water gives the nitrobutylidenehydrazino derivative (XV), which is cyclized with PPE as before yielding N-methyl-3-(2-nitroethyl)-1H-indole-5-methansulfonamide (XVI), which is reduced with H2 over Pd/C in ethyl acetate to afford the 2-aminoethyl compound (XVII). Finally, this compound is methylated with ICH3 and NaHCO3 or with formaldehyde and NaBH4
