反応手順

In Scheme 2, Step A, the phthalimide group of the tetrahydrocyclopenta[b]indole of formula (2) is cleaved with methylamine to provide an aminotetrahydrocyclopenta[b]indole of formula (3). Preferred conditions use a solvent such as ethanol at a temperature of about 0 to 35° C., for 3 to 24 hours. The resulting by-product is removed by making the pH alkaline and filtering the resultant precipitate. The product is isolated from the filtrate by precipitation with water and 10% NaOH.
