Procedure

(Related to methods described in Alabaster, C. T. et. al., J. Med. Chem. 1988, 31, 2048–2056.) 3,3-Dimethoxypropanoic acid methyl ester (14.25 g, 96.2 mmol) in THF (100 mL) was treated with LiOH.H2O (2.5 g, 106 mmol) and H2O (2 mL). The mixture was brought to reflux for 4 hours, cooled to room temperature and azeotropically dried from THF (4 times) to provide white solids (13.3 g).
