10 parts of freshly distilled p-methoxyphenylacetaldehyde in 20 parts of sodium-dried dioxan was added to a suspension of 17 parts of benzhydrylammonium hypophosphite in 100 parts of sodium-dried dioxan under reflux and under nitrogen as in Example 17 above. 70 Parts dioxan/water was removed. 125 Parts of alcohol was added and DL-1-benzhydrylamino-2-(4-methoxyphenyl)-ethanephosphonous acid, melting point 199°-202°, was obtained.
