実験手順

The procedure was largely as in Example 8. However, solution 1 contained only 20 g of hydroxy-3-(3-thienyl)acrylic acid and 19 g of L-aspartate. The product concentration was 11.5 g/l (58%) after the reaction. After ion-exchange chromatography, 7.9 g (40%) of L-3-(3-thienyl)alanine (2B) were obtained.

後処理
