To a solution of 4-(4-ethoxycarbonyl-thiazol-2-yl)-4-methyl-piperidine-1-carboxylic acid tert-butyl ester (0.6 g, 1.7 mmol) in anhydrous THF (10 mL) was added LiAlH4 (0.1 g, 2.6 mmol) at 0° C. The mixture was kept at 0° C. for 2 hours and the reaction was quenched with EtOH. The solvent was evaporated and the residue was diluted with EtOAc, washed with 1N NaOH, brine. After drying (Na2SO4), the solvent was removed in vacuo, and the residue was purified by silica column chromatography with EtOAc/hexanes to afford the desired product.
