By the combination of equimolar quantities of DL-methionine amide acetate (I) and D-tartaric acid (II) in methanol, the former was resolved into L-methionine amide neutral tartrate and D-methionine amide acidic tartrate, and each tartrate was derived to respective optically active methionine amide acetate and methionine. Combination of (I) and (II) in 2:1 molar ratio in methanol resulted in the separation of L-methionine amide neutral tartrate and D-methionine amide neutral tartrate.
