Following the general procedure for O-alkylation, Method B, a mixture of 2-methyl-5-(thiazol-2-ylamino)phenol (100 mg, 0.48 mmol) and Cs2CO3 (158 mg, 0.48 mmol) in acetone (4.4 mL) was treated with a freshly prepared solution of 2-furylbromomethane in ether (0.85 mL, 0.44 mmol) at room temperature. After 2 h Cs2CO3 (150 mg, 0.46 mmol) was added and stirred for 5.5 h at rt. The title compound was obtained after purification by flash chromatography on silica gel (hexane:EtOAc 3/1) in 36% yield (50 mg).
