This material was produced from 6-chloro-5-nitro-oxindole (1 eq) and BH3 /THF (6 mol eq.) utilizing a method analogous to that described for 6-chloro-5-fluoro-indole (Preparation 29) in 99% yield (contaminated with some 6-chloro-5-nitro-indoline) and used directly in the subsequent borane/pyridine reduction.
