Rx-ID: 39059092 View in Reaxys 3/14 Yield

Conditions & References General procedure: To a solution of 4’-Fluoro-2,3-di-oxotryptamine (3b, 644 mg, 3.12 mmol) in THF (30 mL), a 1.0 M LiAlH4/THF solution (16 mL, 16 mmol) was added slowly and the mixture was refluxed for 18 h. The reaction was quenched with water/THF (1/1) and made basic (pH 10) with 3 N aqueous NaOH. The solids were filtered through Celite; the filtrate was dried with anhydrous MgSO4and concentrated. The crude material was purified by automated flash chromatography (silica gel, 20percent MeOH/DCM) to obtain 130 mg of colorless oil (23percent). This material was dissolved in diethyl ether (100 mL) and MeOH (1 mL) and a solution of Fumaric Acid (90 mg, 0.77 mmol) in MeOH (9 mL) was added. The reaction stirred at room temperature for 60 h and the resulting solids were filtered, washed with ether and dried. The dry solids were recrystallized (MeOH/ethyl acetate) to yield 70.3 mg of product With lithium aluminium tetrahydride in tetrahydrofuran, Time= 18h, Reflux Blough, Bruce E.; Landavazo, Antonio; Decker, Ann M.; Page, Kevin M.; Partilla, John S.; Baumann, Michael H.; Rothman, Richard B.; Bioorg.
