実験手順

12.5 parts of α-L-aspartyl-L-phenylalanine methyl ester hydrochloride dihydrate was dissolved in 100 parts by volume of water and aqueous sodium carbonate added to pH3, then heated to 60° C. and adjusted to pH4.6. The reaction mixture was cooled to 5° C. for three hours and the precipitate was collected on a filter and dried for 18 hours under vacuum at 60° C. to give 7.6 parts α-L-aspartyl-L-phenylalanine methyl ester.
