実験手順
Ethyl 5-chloro-3-phenylsulfonylindole-2-carboximidate is reacted with an equimolar amount of cyanamide in absolute methanol (according to the procedure of K. R. Huffman and F. C. Schaefer (J. Org. Chem., 28, 1812 (1963)). After 30-60 minutes the solvent is removed and the residue purified by silica gel chromatography to afford the title compound.
