Following the general procedure for O-alkylation, Method A, a mixture of 2-methyl-5-(thiazol-2-ylamino)phenol (70 mg, 0.34 mmol) and K2CO3 (52 mg, 0.32 mmol) in acetone (4.4 mL) was treated with benzyl bromide (58 mg, 0.34 mmol) at RT. Reaction control by TLC showed full conversion after 2 h 30 min. Subsequent benzyl bromide (20 microliter) and K2CO3 (20 mg) were added and stirred over night The title compound was obtained after purification by flash chromatography on silica gel (hexane:EtOAc 3/1) in 58% yield (58 mg).
