Reaction Steps

A solution of 7-iodo-2-methyl-1H-indol-5-ylamine hydrochloride XVII (1.9 g, 6.158 mmol) in N,N-dimethylformamide (30 mL) at 25° C. was treated with sodium dicyanamide (1.37 g, 15.397 mmol) and then warmed to 45° C. for 4 h. The resulting mixture filtered and concentrated in vacuo and the residue treated with water (20 mL). The resulting mixture was allowed to stand at 25° C. for 2.5 h during which time a solid formed. The solid was collected by filtration and washed with water, resuspended in methanol, filtered and dried to give N″-cyano-N-(7-iodo-2-methyl-1H-indol-5-yl)guanidine XVIII (0.88 g, 42%) as a light grey solid: LRMS for C11H10IN5 (M−H)+ at m/z=338.
