실험 절차

LAH (2.25 g, 59.3 mmol) was slowly added to 150 mL of THF. (1-Methyl-piperidin-4-yl)-acetic acid methyl ester (Step B) in 30 mL of THF was added dropwise to the LAH in THF and the resulting mixture was stirred for 4 h. Water (2.26 mL), 2.26 mL of 15% NaOH and 6.78 mL of water were carefully added and stirring was continued for 30 min. The mixture was filtered through Celite®, the solids were washed with EtOAc and the filtrate was evaporated, giving 2-(1-methyl-piperidin-4-yl)-ethanol as a yellow oil.
