In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 492-98-8 as follows. 492-98-8

A mixture of CdCl2¡¤2.5H2O (0.1mmol, 30mg), H2biim (0.1mmol, 10mg) and H2ip-OH (0.1mmol, 20mg) and H2O (8mL) was adjusted to pH 5.0 with 0.05 mol L-1 NaOH solution. It was then sealed in a 25mL Teflon reactor and heated at 150 C for 72 h. The mixture was cooled to room temperature after 40 h. Slightly purple crystals were obtained. Yield: 42 % based on the Cd(II) salt. Anal. Calc. for C11H7N2O5Cd: C, 36.70; H, 1.95; N, 7.79. Found: C, 36.76; H, 1.95; N, 7.80%. IR (KBr, cm-1): 3461 (m), 3058 (w), 2930 (w), 2866 (w), 1630 (s), 1583 (s), 1508 (m), 1397 (s), 1333 (s), 1291 (s), 1208 (m), 1165 (w), 1098 (w), 1014 (w), 859 (s), 750 (s), 661 (m), 428 (w).
