Procedimiento

Twenty four grams of DL-valine and 19.3 g of N-benzoyl-L-alanine were suspended in 200 mL of deionized water. The suspension was heated to 95° C. to form a clear solution, which was cooled slowly. When the solution was cooled to room temperature after 2 hours, the precipitated crystals were separated by filtration, washed with 50 mL of deionized water, and dried to obtain 26.8 g of crystalline L-valine N-benzoyl-L-alanine complex (L-valine to N-benzoyl-L-alanine molar ratio of 1:1).
