合成路线1
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.
