Reaction Steps
To a solution of methyl [(9-amino-1,2,3,4-tetrahydroacridin-1-yl)oxy]acetate (13.7 g) in tetrahydrofuran (200 ml) was added potassium t-butoxide (6.7 g). The reaction mixture was stirred at ambient temperature for 2.5 hrs and evaporated. The residue was stirred in dilute potassium carbonate solution/ethyl ether. The precipitate was collected and dried. A 3.5 g sample was recrystallized twice from methanol/water, passed through a column of basic alumina (5% methanol/ethyl acetate) and recrystallized from methanol to give 1.37 g (39%) of product, mp 173°-175° C.
