Procedure

General procedure of coupling alcohol to aryl halides: A mixture of 4-[6-(2-fluoro-4-iodo-phenylamino)-5-methyl-pyrimidin-4-yloxy]-piperidine-1-carboxylic acid isopropyl ester (103 mg, 0.2 mmole), cesium carbonate (130 mg, 0.4 mmole), copper iodide (8 mg, 0.04 mmole), and 1, 10-phenanthroline (14 mg, 0.08 mmole) in 2-methanesulfonyl-ethanol (3 mL) was heated under microwave irradiation at 150° C. for 1 hour. The crude mixture was purified by HPLC to provide Compound A95 as a yellow solid (3 mg, 3%). Exact mass calculated for C23H31FN4O6S 510.2, found 511.3 (MH+).
