A solution of 3-[(2,4,5-trifluorophenyl)sulfonyl]dihydrofuran-2(3H)-one (126 mg, 0.45 mmol) and 3-((1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-methylethyloxy)-5-hydroxy-N-(1-methyl-1H-pyrazol-3-yl)benzamide (203 mg, 0.50 mmol) in acetonitrile (3.5 mL) was treated with caesium carbonate (650 mg, 2.0 mmol) and heated in a microwave reactor at 150° C. for 1.5 hours. The reaction mixture was filtered and concentrated in vacuo. The residue was then chromatographed on silica, eluting with a gradient of 0 to 10% methanol in ethyl acetate, to afford the title compound (78 mg).
