Reaction Steps
A mixture of 13.6 parts anisaldehyde and 8.3 parts ammonium hypophosphite in 100 parts xylene was refluxed with water separation. The xylene was cooled, decanted and the residue boiled with ethanol to give a white solid. Filtration gave DL-1-amino-p-methoxyphenylmethanephosphonous acid, melting point 239°-241° (dec.).
