Reaction Steps

Hypophosphorous acid (100%, 15.8 parts) dissolved in absolute ethanol was added to a stirred solution of 41.3 parts isobutylidenebenzhydrylamine in absolute ethanol. An exothermic reaction occurred. After standing one hour the reaction was filtered and the white solid dried in vacuo. There was obtained DL-1-benzhydrylamino-2-methylpropanephosphonous acid, melting point 191° (dec.).
