Reaction Steps

3-(4-Hydroxy-phenyl)-isoxazole-5-carboxylic acid amide (which may be prepared as described in Preparation of Intermediate 2; 50 mg, 0.24 mmol), K2CO3 (37 mg, 0.27 mmol) and tetrabutylammonium iodide (9 mg, 0.024 mmol) were taken up in DMF (2.4 mL). 2-Chloro-5-fluorobenzyl chloride (55 mg, 0.24 mmol) was added and the reaction mixture was stirred at room temperature overnight. The solvent was evaporated and the residue was purified by high-throughput purification to give 3-[4-(2-chloro-5-fluoro-benzyloxy)-phenyl]-isoxazole-5-carboxylic acid amide (3.8 mg, 4%). LRMS (ESI+): m/z [M+CH3CN+H]+ 387.9.
