실험 절차

Caesium carbonate (523 mg) was added to a solution of 3-hydroxy-5-{[(1S)-2-hydroxy-1-methylethyl]oxy}-N-(1-methyl-1H-pyrazol-3-yl)benzamide (234 mg) and 1,2,4-trifluoro-5-(methylsulfonyl)benzene (169 mg) in acetonitrile (5 mL) was added. The mixture was heated in a sealed microwave vial to 160° C. for 7000 seconds and left to cool before being filtered and washed with acetonitrile (10 mL). The filtrate was evaporated in vacuo and chromatographed on silica, eluting with 0 to 10% methanol in ethyl acetate. This gave incomplete resolution so the mixture was purified by preparatory HPLC using a gradient of 5 to 95% acetonitrile in water to afford the desired compound (5.1 mg)
