Reaction Steps

To a microwave vial add 4-hydroxy-4-[4-(3-trifluoromethyl-phenyl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazol-2-yl]-piperidine-1-carboxylic acid tert-butyl ester (0.453 g; 1.00 equiv; 836.28 μmoles; 453.00 mg), ethanol (5 mL; 85.88 mmoles; 5.00 mL; 3.96 g), and hydrogen chloride (5 mL; 5.00 mmoles; 1N aqueous) and heat to 70° C. in a microwave with stirring on and hold for 4 h. Concentrate the reaction mixture to give 4-[4-(3-Trifluoromethyl-phenyl)-1H-imidazol-2-yl]-piperidin-4-ol salt (0.32 g; 1.00 equiv; 832.84 μmoles; 320.00 mg; 99.59% yield).
