실험 절차
First, 5.0 g (31 mmol) of L-glutamic acid-γ-methyl ester was suspended in 15 mL of methanol. To this, 3.4 g (34 mmol) of acetylacetone and 2.3 g (31 mmol) of t-butylamine were added. The mixture was heated at 60° C. for 2 hours. Subsequently, 20 g (310 mmol) of 70% ethylamine was added to the mixture and the same procedure as in Example 1 was performed to obtain 3.6 g of theanine (yield: 66.7%). The obtained theanine had the same purity as high as in Example 1.
