**2.4 Synthesis of 1-(3,5-dimethylphenyl)-4,5-dimethyl-2-phenyl-1***H***-imidazole hemihydrate (C19H20N2.0.5H2O): DMPDMPIHH**

15 mmol of pure butane-2,3-dione in 10 ml of ethanol was combined with 15 mmol of 3,5-xylidine, 15 mmol of ammonium acetate, and 15 mmol of benzaldehyde for an hour at a constant temperature of 333 K. The subsequent steps are conducted in the manner specified in DMDPIMH. The yield was 1.91 g or 46% (**Figure 1**). The X-ray diffraction data were gathered with a suitable single crystal [13].
