[0186] Preparations of the above-mentioned dosage forms can be carried out in accordance with known production methods commonly used in the field of pharmaceutical preparations. At this time, if necessary, it can be produced containing excipients, binders, lubricants, disintegrants, sweeteners, surfactants, suspending agents, emulsifying agents, etc., which are conventionally used in the field of pharmaceutical preparations.
[0187] Tablets can be prepared, for example, by containing excipients, binders, disintegrants or lubricants. The preparation of pellets and granules can be carried out, for example, with excipients, binders or disintegrants. In addition, powders and capsules can be prepared, for example, with excipients. The preparation of a syrup can contain a sweetener, for example. The preparation of an emulsion or a suspension can be carried out by containing, for example, a surfactant, a suspending agent, or an emulsifying agent.

Embodiment
[0200] Hereinafter, although an Example and a reference example demonstrate this invention in detail, this invention is not limited to these.
[0201] In the following description, the solvent names shown in the NMR data indicate the solvents used for the measurement. In addition, the 400 MHz NMR spectrum was measured using the JNM-AL400 nuclear magnetic resonance apparatus (made by JEOL Ltd.). The chemical shift is based on tetramethylsilane, expressed in δ (unit: ppm), and the signals are represented by s (single line), d (double line), t (triple line), q (quadruple line), quint ( Quintuplet), sept (sevenfold), m (multiplet), br (broad peak), dd (double doublet), dt (double triplet), ddd (double doublet doublet) , dq (double quartet), td (triple double line), tt (triple triple line) represent. The ESI-MS spectrum was measured using Agilent Technologies 1200 Series, G6130A (manufactured by Agilent Technology). All solvents used commercially available solvents. For flash c...

[0203] (Reference Example 1) Synthesis of 3-(1H-imidazol-2-yl)acrylic acid (E)-benzyl ester:
[0204] [chemical formula 9]
[0205]
[0206] To a suspension of sodium hydride (55%, 1.12g, 25.6mmol) in tetrahydrofuran (40.0mL), add benzyl dimethylphosphorylacetate (5.12mL, 24.4mmol) at 0°C, and the reaction solution was placed in the same Stir at temperature for 1 hour. To the reaction liquid, 1H-imidazole-2-carbaldehyde (2.46 g, 25.6 mmol) was added at 0° C., and the reaction liquid was stirred at room temperature for 60 hours. To the reaction liquid, saturated aqueous ammonium chloride solution was added, followed by extraction with ethyl acetate. The organic layer was washed with 10% aqueous sodium chloride solution, dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by flash column chromatography (silica gel, chloroform / methanol) to give (E)-benzyl 3-(1H-imidazol-2-yl)acrylate (0.380 g, 1.6...
