(4-Benzyloxy-phenyl)-acetic acid (50 mg, 0.2 mmol, 1 eq) was stirred with 1 mL of thionyl chloride at 80° C. for approximately three hours. The completion of the reaction was checked by TLC. Excess thionyl chloride was removed in vacuo, the residue was dissolved in dichloromethane and added to a mixture of 3-tert-butyl-isoxazol-5-ylamine (28 mg, 0.2 mmol, 1 eq) and DIEA (35 μL, 0.2 mmol, 1 eq). The reaction was stirred overnight at 45° C. The solvent was removed and the product purified by HPLC. Yield: 42 mg (57%), LC/MS [MH+] 365.
