関与物質

反応手順

AlCl3 (0.733 g, 5.50 mmol) is added to a solution of 7-(4-methoxybenzyl)-5-methyl-3-(phenylamino)-1H-pyrazolo[3,4-d]pyrimidine-4,6(5H,7H)-dione (0.692 g, 1.83 mmol) and anisole (40 μL, 0.367 mmol) in 1,2-dichloroethane (10 mL) under argon. The reaction mixture is stirred at room temperature for 30 min, and then quenched with water with cooling. The resulting suspension is filtered through a layer of celite and the celite is washed with MeOH (20 mL). The product is eluted from the celite with a large amount of THF. The THF eluent is evaporated to afford 0.47 g of product (Yield: 99%). MS (FAB) m/z 258.2 [M+H]+.
