Sample Preparation Procedure The HCl salt was dissolved in 0.5 mL water in a test tube, and 1 drop of 30% NaOH solution was added, causing the clear solution to turn cloudy white. 1 mL dichloromethane was added to the test tube, which was shaken thoroughly using a vortex mixer. The test tube was spun in a centrifuge to separate the organic and aqueous layers. The bottom organic layer was retrieved with a pipette and placed in another clean test tube. Most of the solvent was evaporated from the tube using a flow of nitrogen gas, and the remaining solution was used to create a film on the diamond window for ATR-IR.
