合成路线2

该中间体在本合成路线中的序号：(III)

Tetrahydrobenzo[cd]indol-2-one (IV) is selectively alkylated at position 2a with 1,4-dibromobutane (V) in the presence of NaH to provide the bromobutyl derivative (VI). Then, condensation of bromide (VI) with amine (III) employing K2CO3 in DMF leads to the title compound.
