EXAMPLE 11; N-(3-{2-[4-(cyclopentylmethoxy)phenoxy]-1,3-thiazol-5-yl}-1-methylprop-2-yl)acetamide; EXAMPLE 11A; 4-[(5-bromo-1,3-thiazol-2-yl)oxy]phenol; A mixture of hydroquinone (440 mg, 4.0 mmol), 2,5-dibromothiazole (486 mg, 2.0 mmol) and potassium carbonate (276 mg, 2.0 mmol) in DMF (4 mL) was heated in a microwave oven at 180° C. for 10 minutes. The mixture was partitioned between ethyl acetate and saturated NaHCO3 (30 mL, 1:1). The organic phase was washed with brine (×3), dried (MgSO4), filtered and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel column with ethyl acetate/hexane (1/2) to provide 408 mg titled compound (yield 76%).
