The synthesis of BBR-3438 has been described: The cyclization of 6-chloro-9-fluorobenz[g]isoquinoline-5,10-quinone (I) with 2-hydroxyethylhydrazine (II) in hot pyridine gives 2-(2-hydroxyethyl)-5-chloroindazolo[4,3-gh]isoquinolin-6(2H)-one (III), which is condensed with N-(2-aminoethyl)-N-methylcarbamic acid tert-butyl ester (IV) in hot pyridine yielding the corresponding 5-[2-[N-(tert-butoxycarbonyl)-N-methylamino]ethylamino] derivative (V). The mesylation of the OH group of (V) with mesyl chloride and triethylamine in dichloromethane affords the mesylate (VI), which is condensed with hot ethanolamine (VII) to give the protected compound (VIII). Finally, this compound is deprotected with HCl yielding BBR-3438.

合成路线3

该中间体在本合成路线中的序号：(I)

The reaction of (2-hydroxyethyl)hydrazine (I) with MsCl in pyridine gives the trimesylated compound (II), which is treated with LiCl in refluxing acetone to yield 1-(2-chloroethyl)-1,2-bis(methanesulfonyl)hydrazine (III) (1). Finally, this compound is condensed with methyl isocyanate (IV) by means of TEA in acetonitrile to afford the target semicarbazide.
