実験手順

7.2 parts of isobutyraldehyde in 15 parts of sodium-dried dioxan was added to a suspension of 25 parts of benzhydrylammonium hypophosphite in 150 parts of sodium-dried dioxan under reflux. 80 Parts of dioxan was removed and 150 parts of alcohol added. After cooling the mixture was filtered to give DL-1-benzhydrylamino-2-methylpropanephosphonous acid, melting point 189°-192° identical to that obtained in Example 2A.
