反応手順
The same esterification procedure as in Example 1 was followed with the exception that the L-phenylalanine was replaced with 182.6 g of L-lysine hydrochloride and that 182.6 g of methanol and 87.3 g of hydrochloric acid were used. Following cooling in order to deposit the crystals, the latter were collected by filtration and then dried to obtain 196.2 g (81.3% yield) of L-lysine methyl ester dihydrochloride having a purity of 96.6% and containing 0.2% of water and 1.3% of L-lysine hydrochloride.
