Reaktionsschritte

Lithium aluminum hydride (500 mg) was added to a stirred solution of ethyl 7-methoxy-9-oxoxanthene-2-carboxylate (1g) in THF (100 ml). The reaction mixture was stirred at room temperature under nitrogen for 5 hours. Water and MgSO4 were added. The inorganic solids were filtered off and washed with ethyl acetate. The filtrate and washings were combined and evaporated to give the crude product. Recrystallization from ethyl acetate gave white crystals (0.82 g, 84%), mp. 142°-143°.
