Procedure

1 N Sodium hydroxide (80 mL) was added to a solution of D-valine benzyl ester trifluoroacetic acid salt (10 g, 31.1 mmol) in methylene chloride (80 mL) and the reaction mixture was stirred until all the starting material was converted to the free amine. The organic phase was collected and washed with brine, dried over magnesium sulfate, and concentrated to give D-valine benzyl ester (5.35 g) as a clear oil.
