Procedure

To the solution of DL-3-aminoisobutyric acid (CAS number: 144-90-1, Aldrich) (2.7 g, 26.4 mmol) in MeOH (50 mL) was added SOCl2 (6.17 g, 52.8 mmol) dropwise at 0° C. under N2 atmosphere. The reaction was refluxed for 18 hours. The solvent was removed in vacuo to give crude Compound W which was used directly in the next step.
