To a stirred solution of methyl 4-{2-[2-(acetylamino)-1,3-thiazol-4-yl]ethyl}benzoate (1.8 g) in dry tetrahydrofuran (36 ml) was added dropwise 1.0 M diisobutylaluminium hydride solution in toluene (20.7 ml) at −78° C. over 15 minutes under nitrogen atmosphere. The reaction mixture was stirred at room temperature for 1.5 hours, and then the reaction was quenched with water (1 ml). The mixture was stirred at room temperature for 30 minutes, dried over anhydrous magnesium sulfate, and filtered through a pad of Celite. The solvent was evaporated in vacuo. The residual solid was washed with ethyl ether to give N-(4-{2-[4-(hydroxymethyl)phenyl]ethyl}-1,3-thiazol-2-yl)acetamide (1.03 g) as a colorless solid.
