Methyl formate → Nalpha-formyl-DL-methionine amide

Participants

Reaction Steps

30 g (0.20 mole) DL-methionine amide were agitated with 250 ml methyl formate for two days at room temperature, during which fine, slightly yellow crystals developed. They were filtered off and recrystallized out of a mixture of 150 ml hexane and 160 ml ethanol. After cooling off, filtering, washing and drying, 23 g (55%) Nα -formyl-DL-methionine amide were obtained in the form of colorless crystals with a melting point of 121-122° C.
