Reactant 2

HCID 213258821-Benzhydrylamino-2-methylpropanephosphonous acid

HCID 213258931-Benzhydrylamino-1-(2-thienyl)-methanephosphonous acid

Product 1

HCID 213259051-Amino-1-(thien-2-yl)-methanephosphonous acid

Procedure

The procedure described in Example 36B was repeated using DL-1-benzhydrylamino-1-(2-thienyl)-methanephosphonous acid instead of DL-1-benzhydrylamino-2-methylpropanephosphonous acid to give DL-1-amino-1-(thien-2-yl)-methanephosphonous acid, melting point 229°-230°.
