1-(t-Butoxycarbonyl)-3-(chloromethyl)-6-nitroindoline was coupled with N-[(butoxycarbonyl)methyl]-2-carboxyindole-6-carboxamide by the method described above and the product recrystallised from EtOAc to give with N-[(butoxycarbonyl)methyl]-2-[[3-(chloromethyl)-6-nitroindolin-1-yl)carbonyl]indole-6-carboxamide as a yellow solid (69%), mp 286° C.
