SOCl2 (7.0 mL) was added slowly to MeOH (100 mL) at −20° C. (bath temp), and stirred for 30 min. 2-Amino-4-bromo-butyric acid hydrobromide (5.0 g, 19 mmol) was then added and the reaction mixture was stirred O/N at rt. Concentration in vacuo gave the title compound as a viscous liquid which become solid on standing: yield 5.2 g (99%).
