실험 절차

A suspension of Example 1C (2 g, 9.43 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxa-borolan-2-yl)aniline (2.5 g, 11.3 mmol), and Na2CO3 (2.2 g, 20.8 mmol) in DME (68 mL) and water (17 mL) was purged with nitrogen, treated with Pd(PPh3)4 (1 g, 0.9 mmol), and stirred at 90° C. for 19 hours. The reaction mixture was cooled to room temperature, concentrated to one-third its original volume, diluted with ethyl acetate (30 mL) and water (20 mL), and filtered. The filter cake was washed with water and ethyl acetate and dried to give 1.25 g of the desired product. MS (ESI(+)) m/e 225 (M+H)+.
