실험 절차

The preparation of metalaxyl is published in the CH-PS 607,888, according to which 2,6-dimethylaniline is first reacted with methyl DL-α-bromopropionate in the presence of sodium hydrogen carbonate as acid binding agent, then methyl N-(2,6-dimethylphenyl)-DL-alaninate thus obtained is acylated with methoxyacetyl chloride to give metalaxyl.
