1-Amino-2-(2-hydroxymethylphenyl)ethane (10.2 g) was dissolved in 40 ml of pyridine, and with stirring under ice cooling, 25 g of 4-nitrobenzoyl chloride was added gradually. The mixture was stirred at room temperature for 4 hours and then at 50° C. for 1 hour, and poured into ice water. The crystals precipitated were washed in water, dried, and recrystallized from tetrahydrofuran-benzene to afford 24.3 g of 1-(4-nitrobenzoyl)-amino-2-[2-(4-nitrobenzoyloxymethyl)phenyl]ethane having a melting point of 168.2° to 169.7° C.
