실험 절차
In Scheme 1, Step C, the phthalimide group of the tetrahydrocyclopenta[b]indole of formula (2) is cleaved with hydrazine or hydrazine hydrate to provide an aminotetrahydrocyclopenta[b]indole of formula (3). Preferred conditions use tetrahydrofuran/ethanol in a mixture of about 20/1 by volume at a temperature of about 40 to 70° C., for 1 to 12 hours. The resulting phthalhydrazide is removed by filtration and the product isolated by concentration of the filtrate.
