Reaction Steps

To a solution of 4-[4-(1-Hydroxy-ethyl)-5-methyl-thiazol-2-yl]-piperidine-1-carboxylic acid tert-butyl ester (0.15 g, 0.46 mmol), 4-methanesulfonyl-phenol (0.08 g, 0.46 mmol) and PPh3 (0.14 g, 0.55 mmol) in THF (5 mL) was added DEAD (0.1 g, 0.55 mmol) at room temperature. The resulting mixture was stirred at room temperature for 30 minutes. The solvent was removed. The residue was purified by flash chromatography on silica gel to afford the desired product. 1H NMR (CDCl3): δ 7.79 (2H, m), 6.94 (2H, m), 5.59 (1H, q, J=6 Hz),), 4.2-4.04 (2H, m), 3.04-2.94 (1H, m), 2.98 (3H, s), 2.86-2.72 (2H, m), 2.39 (3H, s), 2.04-1.96 (2H, m), 1.67 (3H, d, J=6 Hz), 1.66-1.58 (2H, m), 1.42 (9H, s).
