実験手順

15.8 g. of 4-[(2-methyl-1,2-dicarbobenzoxy-hydrazino)methyl]-benzoyl chloride were dissolved in 50 ml. of methylene chloride. This solution was added, while stirring, dropwise to a suspension of 12.6 g. of 2-hydroxy-3,3,3-trichloro-propylamine in 150 ml. of methylene chloride. Stirring was continued for 2 hours at room temperature and 30 minutes at 40°, whereupon 50 ml. of water were added thereto. The product was worked up according to Example 3 and treated with hydrogen bromide in glacial acetic acid. The crystalline crude material was recrystallized from ethanol/acetonitrile/ether, yielding 4-[(2-methylhydrazino)-methyl]-benzoic acid [2-hydroxy-3,3,3-trichloropropyl]amide hydrobromide melting at 187°-189° (dec.).
