実験手順
0.026 Part of 2-(2-amino-4-chlorophenoxy)benzyl alcohol is dissolved in 0.5 part pyridine and 0.5 part by volume acetic anhydride and allowed to stand at room temperature for 16 hours. The solvent is removed by evaporation under a nitrogen atmosphere and the resultant residue chromatographed on 0.6 part silicic acid. Elution with a 5:95 mixture of ethyl acetate-benzene and recrystallization from a mixture of ethyl acetate and benzene affords 2-(2-acetamido-4-chlorophenoxy)benzyl acetate. This compound melts at about 83 - 84° C. and is represented by the following structural formula. ##STR6## Elemental analysis shows C, 61.71%; H, 5.30%; Cl, 10.73%; N, 4.01%. The calculated values are C, 61.17%; H, 4.83%, Cl, 10.62%; and N, 4.20%.
