Reaction Steps

Ethyl 2-(4-methylpiperidin-1-yl)-2-phenylacetate (225 mg, 0.86 mmol) and 37% aq HCl (0.52 ml, 17.2 mmol) were dissolved in Dioxane (7 ml) and heated under microwave irradiation into a sealed vial at 100° C. for 8 hours. The solvents were evaporated, the residue was suspended in EtOAc and evaporated. The residue was suspended in EtOAc/Et2O (1/1), sonicated and filtered under suction to obtain 2-(4-methylpiperidin-1-yl)-2-phenylacetic acid hydrochloride (223 mg, 96% yield) as a white solid
