78% | (Synthesis of Compound A) (0152) (0153) 70 mL of an anhydrous THF solution of 10.6 g (42.9 mmol) of <strong>[50548-45-3]1-bromodibenzofuran</strong> was added to a 500 mL, three-necked flask, and stirred at about ?78° C. 27 mL (42.9 mmol) of a hexane solution of 1.58 M n-BuLi was added dropwise, followed by stirring for about 2.5 hours. 85 mL of an anhydrous THF solution of 9.30 g (35.6 mmol) of 3-bromobenzophenone was added dropwise, followed by stirring for about 2 hours and then stirring at room temperature for about 3 hours. After the reaction was complete, a 1 N aqueous hydrochloric acid solution was added thereto and stirred for about 1 hour. The resulting product was washed with water, and the organic phase was concentrated to obtain a material having a candy-like consistency. The material having a candy-like consistency, 50 mL of glacial acetic acid, and 2.4 mL of hydrochloric acid were added to a 500 mL eggplant (e.g., pear-shaped) flask, followed by heating and stirring under a nitrogen atmosphere at about 130° C. for about 2 hours. The reaction mixture was added dropwise to 350 mL of water in a flask stored over ice, thus precipitating white crystals. The solid thus produced was filtered, washed with methanol, and dried. 13.3 g of a white powder was obtained as the target material at a yield of 78percent. (0154) The molecular weight of the product was measured using fast atom bombardment-mass spectrometry (FAB-MS) to be 411, consistent with Compound A. |
