실험 절차

A solution of benzaldehyde (102 ml, 1.01 mol) in ethanol (300 ml) was added to a solution of D-penicillamine (150 g, 1.01 mol) in water (900 ml) at room temperature. The mixture was stirred at room temperature for 15 minutes and under ice-cooling for 1.5 hours, and then the precipitated crystals were filtered off and dried. Acetic anhydride (480 ml, 5.05 mol) was added dropwise to a solution of the obtained crystals in water (700 ml) at 60° C. over 15 minutes. The mixture was stirred at the temperature for 15 minutes, then at room temperature for 15 minutes and under ice-cooling for 1.5 hours, and the precipitated crystals were filtered off and dried to give 252.3 g (89%) of the target compound.
