Procedure
(R)-1-[2-Hydroxy-3-(quinolin-5-yloxy)-propyl]-piperidine-4-carboxylic acid ethyl ester (31) (1.15 g; 3.21 mmol) is dissolved in 21 mL of a 40:40:20 mixture of tetrahydrofuran:water:methanol. Lithium hydroxide (81 mg; 3.37 mmol) is added and the mixture stirred at ambient temperature. After 4.5 hours, the mixture is concentrated in vacuo at 40° C. Further drying on the vacuum pump affords the desired product (32) as a white solid.
