실험 절차

Anastrozole (28.3 mg, 0.096 mmol) and oxalic acid (8.9 mg, 0.099 mmol) were dissolved in 1 mL methanol:acetonitrile (1:1 v/v) solution. Crystals of anastrozole oxalate were obtained from slow evaporation at room temperature in an ambient atmosphere. Crystals of anastrozole oxalate were also obtained via crystallization of anastrozole (38.3 mg, 0.131 mmol) and oxalic acid (10.7 mg, 0.119 mmol) in 1.5 mL methanol:ethyl acetate (1:0.5 v/v) solution. The crystalline form of anastrozole oxalate was characterized by single crystal x-ray diffraction and melting point. (See FIGS. 14 and 15)
