Procedure
A mixture of 5-Bromo-4-methyl-3-phenyl-3H-isobenzofuran-1-one (100 mg, 0.33 mmol), 3,5-dimethylisoxazole-4-boronic acid (93 mg, 0.66 mmol, 2 eq.), 1N Na2CO3 (0.66 mL, 0.66 mmol) and Pd(PPh3)4 (62 mg, 0.033 mmol, 0.1 eq.) in dioxane (20 mL) is stirred at 90° C. for 16 hours. After cooled to room temperature, the mixture is evaporated in vacuo. The residue is purified by preparative-TLC using a petrol ether ethyl acetate mixture to afford the desired compound as a white solid.
