Synthesis of SU-102 was modified from a previously reported procedure . ZrOCl2•8H2O (32 mg, 0,1 mmol), ellagic acid (60 mg, 0,2 mmol), deionized water (2.5 mL), acetic acid (1.0 mL) and N,N-dimethylformamide (DMF, 1.0 mL) were combined in a borosilicate 3.3 glass tube (Duran 12 × 100 mm, DWK Life Sciences). The glass tube was then sealed with a polybutylene terephthalate (PBT) cap containing a PTFE seal and heated at 160 °C in an aluminium heating block for 1 h while stirring. After cooling the glass tube to room temperature, the resulting brown suspension was then centrifuged at 10,000 rpm for 10 minutes and decanted. The remaining yellow solid as then dried overnight at 80 °C.
